Introducing the World’s<br />
First Vector Signal Transceiver<br />
VSA + VSG + User-Programmable FPGA = RF Redefined<br />
Combining a vector signal analyzer and a vector signal generator with a<br />
user-programmable FPGA for real-time signal processing and control, this<br />
vector signal transceiver is a fraction of the size and cost of a traditional<br />
solution. More importantly, the NI PXIe-5644R is the first software-designed<br />
instrument. With NI LabVIEW system design software, you can modify its<br />
software and firmware to create an instrument that meets your exact needs.<br />

Balancing Innovation<br />
with Design Rigor and<br />
Processes<br />
Tom Perkins<br />
Senior Technical Editor<br />
I<br />
have enjoyed the privilege of being involved in design<br />
and development projects—mostly RF and microwave<br />
hardware--at many levels spanning parts of six<br />
decades. Responsibilities range from bottom-up design to<br />
leading teams of engineers and technicians. In recent<br />
years my involvement has, in part, reverted to serving as<br />
an individual contributor, which can be very rewarding.<br />
This led to several patents awards late in my career.<br />
Most projects carry very specific specifications and<br />
very short, defined schedules, requiring examination of the “critical path”<br />
schedule. Schedule slippage almost always leads to higher spending and cost<br />
overruns. Furthermore, in today’s economy, design entities must be responsible<br />
to a “customer” at a higher level up the “food chain.” The customer<br />
usually has rigid, unwavering expectations and specifications which may<br />
have been created by engineers who never get to meet the ultimate supplier/<br />
contractor.<br />
After specifications are created, legalism over the way specifications<br />
are written can be an issue. Both specifiers and suppliers now ponder the<br />
meaning of “will,” “shall,” “must,” “meet,” “goal,” “figure of merit,” “nominal,”<br />
etc. This occurs more in today’s environment due to lack of sustaining<br />
funds for the user to support the supplier design activity and profit-driven<br />
“bottom line.”<br />
R&D Handcuffed<br />
It seems that research and development is mostly relegated to universities,<br />
a few other government funded entities, and occasionally, efforts by<br />
individuals in home garages or basements, e.g., the Varian brothers and<br />
Hewlett-Packard. The development of electronic integrated circuits (and no<br />
doubt many regulations controlling business activity) has lessened the ability<br />
to do the gutsy garage-type activity over the past 40 years because of the<br />
need for specialty assembly capabilities. Many projects these days seem to<br />
expect outcomes that are truly unique and innovative, but carry limited<br />
funding and tight schedules—as if the design process and outcome is entirely<br />
predictable.<br />
Copyright © 2012, Summit Technical Media, LLC<br />
What to Do?<br />
So given this background, engineers’ drive for innovation can be significantly<br />
curtailed by the “bottom line” finances available. Obtaining parts for<br />
6 <strong>High</strong> <strong>Frequency</strong> <strong>Electronics</strong>
experimentation in practically zero<br />
time can require very resourceful<br />
effort because the rigid systems in<br />
place for parts procurement too often<br />
have been established primarily for<br />
production and “just-in-time” receipt.<br />
One partial solution is obtaining<br />
“samples,” but these are sometimes<br />
unreliable parts—and a single failure<br />
can result in quick dismissal of a project<br />
by management. Rigorous design<br />
rules, such as parts derating, design<br />
reviews (Preliminary Design Reviews,<br />
Critical Design Reviews, and Final<br />
Design Reviews) and many “-ilities”<br />
are important. But with tight constraints<br />
on schedules and finances<br />
they often severely limit time for<br />
experimentation.<br />
Suggestions:<br />
• Make a list of solutions very<br />
early in the design process. This would<br />
certainly include the solution proposed,<br />
but might have variants that<br />
could be more or less innovative, and<br />
might save cost.<br />
• Most design efforts involve team<br />
effort and the ability to compromise,<br />
combined with the resolve to do right.<br />
Sometimes you can get your wishes<br />
met by just ‘floating” an idea and letting<br />
others scramble to take credit for<br />
it.<br />
• Keep the design as simple as<br />
possible.<br />
• Try to anticipate how the design<br />
will look when released to production.<br />
Will it survive the test of time going<br />
forward with minimal Engineering<br />
Change Orders and compromises?<br />
• Will it fill a requirement that<br />
could be adapted to some future<br />
upgrade with minimal interface<br />
changes? Can we fill this space with<br />
something better in the future?<br />
• Discuss your ideas with others<br />
in various disciplines outside of engineering<br />
to get their inputs: project<br />
management, QA, reliability, manufacturing,<br />
etc.<br />
• Make the first meeting with the<br />
customer exciting by showing solutions<br />
considered and even making<br />
“mock-ups” of what the product might<br />
look like. Make sure the customer<br />
understands your interpretation of<br />
what they want. Sometimes there is<br />
wide difference between the written<br />
word and what they really need. Get<br />
changes in writing!<br />
• Be practical about where parts<br />
can be obtained. Try to insure that<br />
sample parts are reasonably reliable<br />
and not counterfeit, or rejects.<br />
Finally: remember that not all<br />
projects will be overwhelmingly successful.<br />
Some are praiseworthy but<br />
flawed concepts while others may be<br />
inadequately funded. But while you<br />
cannot be responsible for everything<br />
that happens, never let distractions<br />
interfere with your next good idea.<br />

Learning how to design your product so that it complies<br />
with EMC regulations can save you from a finished<br />
product that fails in compliance testing.<br />
Re-designing or adding fixes to a failed product can<br />
be expensive and time-consuming. In this seminar<br />
you will learn the fundamentals of electro-magnetic<br />
compatibility, including understanding the many<br />
EMC regulatory requirements such as FCC, CE, US<br />
Military, RTCA-DO-160, and those of most foreign<br />
countries. You will learn how to minimize EMC problems,<br />
starting with the design process through final<br />
testing and approval, all of which will be brought to<br />
life through hands-on practical application to real-life<br />
products.<br />

increasing by 1% and diluted EPS increasing by 6%<br />
compared to the prior quarter. Profitability and cash<br />
flow remained strong,” said Jerald G. Fishman,<br />
President and CEO. “Given the economic headwinds<br />
and uncertainty in most regions, we were encouraged<br />
by consistent order patterns among customers and<br />
distributors and by the resilience of our large and<br />
broad-based industrial business, as well as the communications,<br />
automotive, and consumer end markets.”<br />
Mr. Fishman continued, “As a result of higher opening<br />
backlog and stable order patterns, we are planning for<br />
sequential revenue growth in the fourth quarter. We<br />
expect that revenue from the industrial, communications,<br />
and automotive end markets will be similar to<br />
third quarter levels, in line with typical seasonal patterns.<br />
We are expecting sequential revenue growth<br />
from our consumer customers as is typical in the fourth<br />
quarter and also as a result of a strong new product<br />
cycle. In aggregate, we are planning for revenue in the<br />
range of $685 million to $715 million for the fourth<br />
quarter.”<br />
Sherry Hess, VP of Marketing at<br />
AWR Corp., recently noted that a<br />
year has passed since AWR merged<br />

IMS 2012 in June we jointly demonstrated<br />
integration of AWR’s<br />
Visual System Simulator (VSS)<br />
and NI’s LabVIEW within both of<br />
our booths—for example, applications like 802.11ac,<br />
radar and more. At NIWeek 2012, we demonstrated<br />
Behavioral Model Extraction: A <strong>Power</strong> Amplifier<br />
Example, which showcased a PXI system being used<br />
for power amplifier behavioral model extraction that<br />
also embraces AWR’s time delay neural network modeling.<br />
As our second year as ‘A National Instruments<br />

Simulation Procedures for<br />
Successful Low Noise Amplifier<br />
(LNA) Design Using Discrete<br />
Components<br />
By Sonoko Akamatsu, Scott Muir, and Larry Dunleavy<br />
Introduction<br />
Guiding the user through This tutorial is<br />
the stages of a basic low intended to guide the<br />
noise amplifier design user through the stages<br />
and optimization. of a basic low noise amplifier<br />
design and optimization,<br />
with a goal of first-pass fabricated design<br />
success. This will be accomplished by providing<br />
the user with a project tutorial, starting<br />
with the design process and ending with a<br />
comparison between the software simulations<br />
and the model performances. This example<br />
used in this treatment is that of a low noise<br />
amplifier using a Modelithics-developed nonlinear<br />
model for an Avago ATF54143 PHEMT<br />
device along with Modelithics CLR models for<br />
all passive lumped components [1, 2]. The<br />
simulations shown were developed within<br />
Agilent Technologies’ Advanced Design<br />
System (ADS) RF/Microwave circuit design<br />
simulation environment.<br />
Design Process<br />
In this design, a low noise<br />
amplifier application circuit<br />
was demonstrated at 1.9 GHz.<br />
As stated above, the design<br />
was started with a Modelithics<br />
nonlinear model for Avago<br />
ATF54143 PHEMT device and<br />
Modelithics CLR Models were<br />
used for all passive components.<br />
Figure 1 shows a systematic<br />
design process that<br />
can be followed with good success<br />
for cases where a reference<br />
design or application circuit<br />
is available from the vendor. The initial<br />
schematic described in this note was generated<br />
from the manufacturer application note [3].<br />
Modelithics transistor and passive component<br />
models were then used as the basis for optimization<br />
of the performance, along with built-in<br />
ADS microstrip library models for distributed<br />
elements (MLIN, MTEE, etc.). Additional<br />
steps that can be followed to further improve<br />
this design flow would be to include electromagnetic<br />
co-simulation of the microstrip portion<br />
of the circuit and with volume manufacturability<br />
in mind to add a statistical Monte<br />
Carlo analysis including expected variability<br />
of the PCB board material properties and RLC<br />
component tolerances.<br />
Basic Theory<br />
The Noise Figure describes the signal-tonoise<br />
degradation due to a noisy microwave<br />
component. The Noise Figure is defined as the<br />

power at the input due to thermal noise from the input<br />
termination. The Noise Figure can be expressed as<br />
Where SNRi and SNRo are the signal to noise ratio at<br />
the input and output of the component and P No<br />
is the total<br />
available power at the output of the amplifier, P Ni<br />
is the<br />
available noise power due to the input termination and<br />
G A<br />
is the Available <strong>Power</strong> Gain.<br />
An alternate method for calculating the Noise Figure<br />
is expressed as<br />
the model. The S parameters and noise parameters were<br />
obtained from the Modelithics nonlinear model at the<br />
desired bias point and frequency. The results are shown<br />
in Table 2 and Table 3 under drain source voltage 3 V and<br />
gate voltage of 0.562 V. For this condition the simulated<br />
drain current from the model is 60 mA.<br />

are known as noise parameters and<br />
are given by the manufacturer of the transistor or can be<br />
derived experimentally.<br />
To achieve the minimum noise figure, Γ s<br />
= Γ opt<br />
is chosen.<br />
However, simultaneous minimum noise figure and<br />
maximum gain cannot be obtained, in general. Therefore,<br />
the reflection coefficient, Γ s<br />
can be selected that is a compromise<br />
between the Noise Figure and Gain performance<br />
[4]. The Available Gain can be calculated by<br />
Table 3 • Noise Parameters at 1.9 GHz (Vds = 3V, Vgs<br />
= 0.562V, Ids = 60 mA).<br />
The stability factor of the amplifier was simulated<br />
and also calculated by the obtained S-parameters [4]:<br />
For a two port network, unconditional stability is<br />
achieved when these criteria are satisfied: stability factor<br />
K > 1, and |D| > 1. An alternate set of stability criteria<br />
is K > 1 and b >0, with the b corresponding to the<br />
stability measurement given by:<br />
Design Goals<br />
Table 1 shows the design goals for this example LNA.<br />
The design approach and topology followed that determined<br />
by Avago Application Note 1222 as mentioned<br />
above. Series capacitors and parallel inductors were used<br />
for matching networks and a resistive loading method<br />
was chosen to maintain stability. Additionally source<br />
inductance was added to improve the input return loss.<br />
As a result, NF = 0.8 dB and Gain = 16 dB were obtained<br />
by an ADS simulation.<br />
Table 1 • Design Goals.<br />
Device Simulation<br />
Before proceeding to incorporate the application circuit<br />
topology and layout details, device simulation and<br />
stability analysis were performed on the transistor using<br />
Figure 2 graphically shows that the transistor is<br />
potentially unstable at the design frequency band.<br />
Manufacturer Application Circuit<br />
An application circuit was designed based on the schematic<br />
and component parts list in Table 4 provided by the<br />
manufacturer [3]. Series capacitors and parallel inductors<br />
are used for matching networks. To ensure stability,<br />
resistive loads, 51 ohm and 10 ohm are used to improve<br />
input and output bias networks respectively as shown in<br />
Figure 3 below. The design of these bias networks are<br />
such that the effects of the 51 ohm input bias resistor are<br />
isolated from the RF part of the circuit by a 3.3 nH choke<br />
inductor and a 10 pF bypass capacitor, thus increasing<br />
the noise figure. A combination of 10pF and 10 nF were<br />
used for bypass capacitors.<br />
In addition, source inductance was added for an<br />
improvement of input return loss. The measurement data<br />
of the manufacturer information indicates the potential<br />
for, 16 dB Gain at 1900 MHz, 0.7~0.8 dB Noise Figure<br />
from 1900 MHz through 2000 MHz, -6.4 dB Input Return<br />
Loss and -12.5 dB Output Return Loss under Vds = 3V at<br />

Schematic Circuit and Optimization<br />
Optimization is necessary to achieve the performance<br />
listed on the application note since the chosen substrate<br />
thickness and layout for this demonstration is different<br />
than that of the manufacturer’s reference design [3]. In<br />
addition, details like the passive component size and<br />
manufacturer information are not listed in the application<br />
note. The available Modelithics models are tailored<br />
to the specifics of manufacturer component family and<br />
body style and are substrate scalable. Model inputs were<br />
setup for applicability to the 16 mil Rogers 4003 board<br />
chosen for this design. Figure 3 shows the schematic after<br />
optimization.<br />
Figure 4 and Figure 5 include plots of the optimized<br />
simulation results. Simulations show a Gain of 15.8 dB at<br />
1880 MHz, 0.7 dB Noise Figure, -5.4 dB Input Return<br />
Loss and -15.8 dB Output Return Loss under Vds=3V at<br />
Id=55.7mA. This is close to the manufacturer’s performance<br />
[3]. Table 5 shows the updated optimized component<br />
part list using Modelithics Models.<br />

Layout and Fabrication<br />
As mentioned above, a 16mil Rogers 4003 substrate<br />
was used for the board fabrication. RF probe pads and<br />
grounding pads were added into Figure 6 to facilitate<br />
testing with ground-signal-ground (GSG) RF wafer<br />

(TRL) calibration was performed for these 2 port measurements<br />
using custom calibration standards fabricated<br />
on the same boards used for measurement. The results in<br />
Figure 8 show 17 dB Gain was obtained at 1.88 GHz<br />
when the amplifier was tested at a bias point of Vds=3V<br />
at Id=82mA. (Note that the transistor bias current is<br />
slightly different than that simulated due to transistor<br />
fabrication differences. Vds and Vgs values equal the<br />
simulated values, however the fabricated device uses a<br />
higher current.) Figure 8 also shows the comparison<br />
between simulation and measurement. The result shows<br />
the amplifier design achieved first-pass success. It<br />
should be mentioned that bench tuning or tweaking was<br />
done on this design after assembly. Figure 9 illustrates<br />
that the out-of band performance is also well predicted<br />
through 10 GHz. A comparison with measured Noise<br />
Figure is shown in Figure 10. These results show that<br />
simulation with Modelithics models agrees well with<br />
measurement data and verifies the success of the proposed<br />
design flow.<br />

Modelithics models, compared to that achieved with<br />
alternately available models. This included an alternative<br />

Summary and Conclusions<br />
In this note, a 1.9 GHz Low Noise<br />
Amplifier application circuit was described<br />
that demonstrated a first pass success<br />
design approach. Avago ATF 54143<br />
PHEMT device was chosen to satisfy the<br />
low noise requirement. The design flow<br />
started from the manufacturer application<br />
note and was optimized using a Modelithics<br />
model for the transistor and substratescalable<br />
Modelithics Global Models for the<br />
RLC components. A key feature of achieving<br />
first pass success with this design flow<br />
is the ability to account accurately for<br />
vendor specific performance and substrate<br />
effects of the passive models while being<br />
able to optimize the part values chosen to<br />
achieve the desired performance.<br />

Microwave links in<br />
There is a need to the range of 10 – 27 GHz<br />
develop a new are commonly used for<br />
generation of highly point-to-point (P2P) connectivity.<br />
With the phe-<br />
linear, high frequency<br />
chipsets to address nomenal increase of cell<br />
traffic congestion. phone users and demand<br />
for high data rates, link<br />
traffic is getting congested. Since available<br />
channel bandwidth is limited and fixed, link<br />
manufacturers are addressing this traffic<br />
congestion by increasing spectral efficiency<br />
and are using a complex modulation scheme<br />
such as 4 – 1024 QAM.<br />
In order to support this high order modulation<br />
scheme, there is a need to develop a<br />
new generation of highly linear, high frequency<br />
chipsets starting from baseband to<br />
antenna for Tx path and from antenna to<br />
baseband for Rx path.<br />
RFMD has developed a new generation of<br />
chipsets as shown in Figure 1 in the frequency<br />
range of 10 – 27 GHz to address the growing<br />
issue of traffic congestion.<br />
This portfolio includes voltagecontrol<br />
oscillators (VCOs) featuring<br />
state-of-the-art phase noise,<br />
upconverters with best IP3, noise<br />
figure (NF), and LO leakage over<br />
30 dB gain control range, and<br />
downconverters that have<br />
achieved very low NF and high<br />
IIP3 together in their class.<br />
A key to the success of the Tx<br />
chain at a high frequency component<br />
level is the power amplifier.<br />
As the modulation rate is<br />
increased, the PA’s output power<br />
is backed-off, or in other words, PA output<br />
power is dynamically adjusted during link<br />
operation. The PA should be capable of maintaining<br />
a high level of intermod suppression<br />
(C/I3) at varied output power. In addition, it<br />
needs to have a decent noise figure to minimize<br />
error vector magnitude, (EVM), especially<br />
when the PA input signal contains<br />
higher order modulations.<br />
All RFMD PAs referenced in this article<br />
have been designed with these constraints and<br />
limitations in mind and they are packaged in a<br />
6 x 6 QFN package. RFMD’s 10 – 13 GHz linear<br />
PA (RFPA1002) covers 10, 11, and 13 GHz<br />
bands of point-to-point (P2P) link. This PA has<br />
a small signal gain of 26±1 dB, OIP3=37 dBm<br />
at 28 dBm/DCL (Vd=4V, 982mA) and 42 dBm<br />
(at Vd=7V, 1A). The P1dB of this PA is ~+33<br />
dBm. It can also be used as a VGA by adjusting<br />
the gate control voltage. For gain dynamic<br />
range of 15 dB, Pdiss varies from 1.25 W to 6.0<br />
W, worst case IM3 for entire gain dynamic<br />
range is >46 dBc at Pin = -15dBm.<br />

34 <strong>High</strong> <strong>Frequency</strong> <strong>Electronics</strong><br />
The RFPA1003 is a 14.4 - 15.4 GHz high linearity PA<br />
and it has been designed for 15 GHz band P2P link. It<br />
has 25 dB gain, IM3=50dBc at P OUT<br />
=20dBm/DCL and<br />
35dBc at P OUT<br />
=28dBm/DCL. P1dB of this PA is +32.5<br />
dBm and OIP3=42.5 dBm at P OUT<br />
=28dBm/DCL.<br />
The RFPA1702 is a 17.7 - 19.7 GHz linear PA. It is<br />
designed for 18 GHz P2P link. It has 25 dB gain,<br />
IM3=52dBc at P OUT<br />
=20dBm/DCL and 32.5dBc at<br />
P OUT<br />
=27dBm/DCL. P1dB of this PA is +31.0 dBm and<br />
OIP3=41dBm at P OUT<br />
=28dBm/DCL. Its power dissipation<br />
is ~7.0 W and NF~7.0 dB. With over 15 dB gain<br />
control, it consumes 2 to 6W dc power and OIP3 varies<br />
from 20 to 40 dBm. The minimum IM3 is >55dBc for<br />
Pin=-15dBm/DCL. All of these PAs have been internally<br />
fabricated using 0.25µm PHEMT technology and packaged<br />
in a 6 x 6 QFN package.<br />
Circuit Design<br />
The key to circuit design is the device model. This<br />
model should be able to accurately predict small and<br />
large signal behavior including<br />
P1dB and IM3. The model, which is<br />
developed using DC-IV and<br />
[S]-parameter over various bias<br />
voltages, accurately predicts DC,<br />
[S]-parameters, P1dB and Psat performance.<br />
Such models usually<br />
over predict IM3, and its contours<br />
are sometimes severely dislocated<br />
on the Smith Chart compared to<br />
measured contours. RFMD’s PAs<br />
are designed based on a combination<br />
of measured load-pull data and<br />
modified device models to properly<br />
incorporate IM3 behavior and<br />
device scaling based on IM3.<br />
A good technique to PA design is<br />
to partition the spec into number of<br />
stages and then decide the device<br />
size for each stage that should provide<br />
required gain, power, and IM3<br />
per stage and inter-stage drive<br />
ratio. To design a linear power<br />
amplifier one should look for high<br />
gain and best possible IM3 for specified<br />
output power and each device<br />
should be biased for a little higher<br />
Idss compared a saturated power<br />
amplifier design. Normally a saturated<br />
power amplifier is biased<br />
close to deep class AB condition.<br />
Agilent’s ADS and Momentum have<br />
been used to design power amplifiers<br />
discussed here. Voltage and current<br />
probes have been used at all<br />
parallel nodes feeding and combining<br />
signal and power to active<br />
device. This helped to determine to<br />
maintain close to identical impedances<br />
at all similar nodes and thus<br />
minimize odd-mode problem. Due<br />
to inter-coupling among feed network,<br />
impedance mismatch occurs<br />
that cause odd-mode stability<br />
issues. To suppress odd-mode insta-

outline package drawing. The<br />
main objective of PA design was<br />
to get the best possible IM3 performance<br />
at P OUT<br />
(total) =28<br />
dBm. Better BW or Psat can be<br />
achieved if IM3 is not the main<br />
design criterion.<br />
bility, proper value resistors have been added at gates<br />
and drains. ADS S-probe method has been used to check<br />
inter-stage stability. Figure 2 is an example of the<br />
design steps used for design of these PAs. Figure 3a<br />
shows die photographs of 10, 11, 13, 15, and 18 GHz<br />

Figures 4a - 4f show measured<br />
performance of RFPA1002.<br />
This PA covers 10, 11, and 13<br />
GHz bands of P2P application.<br />
All the measurements are taken<br />
at Vd=6.5, Id (total) =1.07A<br />
unless otherwise noted. Figures<br />
4d - 4f show some of the important<br />
performance plots of this<br />
PA. Figure 4a shows gain versus<br />
frequency behavior over<br />
temperature and Figure 4b<br />
shows OIP3 versus frequency at<br />
drain voltage from 4 to 7V, 0.5<br />

(SCL) P OUT<br />
= 17dBm (or 20 dBm<br />
total power).<br />
Table 1 shows DC power dissipation<br />
corresponding to<br />
Figure 4b. Figure 4c shows<br />
OIP3 improvement with the<br />
increase in DC power dissipation<br />
from 6.8 W to 8.5 W, it<br />
shows > 1.5 dBm improvement<br />
in OIP3 especially at lower frequency<br />
and for P OUT<br />
= 25dBm/<br />
SCL. The main reason for this<br />
improvement could be due to<br />
slightly mismatched IM3 loadline<br />
between simulation and<br />
measured device output load.<br />
Figures 4d - 4f show measured<br />
performance of the PA as a<br />
VGA. PA gain has been varied<br />
using gate bias. Figure 4d shows<br />
variation of OIP3 versus gain,<br />
total gain was varied about 15<br />
dB and OIP3 was measured at<br />
constant input power=-15dBm/DCL. Figure 4e shows<br />
how gain varies with Vg. A >15dB gain dynamic range<br />
has been achieved by adjusting gate bias. Figure 4f<br />
shows change in DC power dissipation with variation of<br />

Conclusion<br />
The performance of RFMD’s linear power<br />
amplifiers is summarized in Table 2. These PAs<br />
demonstrate high gain and high IM3/OIP3 values<br />
at high P OUT<br />
(total) = 28 dBm for 10, 11, 13,<br />
and 15 GHz band applications. For 18, 23, and<br />
26 GHz bands, the IM3/OIP3 was measured at<br />
P OUT<br />
(total) = 27 and 26 dBm. These PAs show<br />
very good performance as VGAs and, by adjusting<br />
gate bias, a gain dynamic range of >15 dB<br />
can be achieved. These PAs maintain decent<br />
IM3/OIP3 performance, a much desired feature<br />
to dynamically adjust power consumption of a<br />
PA. IM5 performance of the PAs is >60 dBc at<br />

Wireless Sensor Network Market to<br />
Exceed 80M Units Shipped<br />
The wireless sensor network market, led by ZigBee,<br />
grew ten-fold from 2007 to 2010 and exceeded 45 million<br />
annual shipments in 2011. “Strong growth is expected for<br />
2012 and beyond as ZigBee pervades the home automation<br />
and home entertainment markets, while Smart Meters<br />
continue to be rolled out across the globe,” commented<br />
Peter Cooney, wireless connectivity practice director.<br />
Smart metering is the largest market for ZigBee in<br />
2012 and will continue to be the major market growth<br />
driver as global roll outs of smart meters continue apace.<br />
ZigBee/RF4CE use in the home environment will also be a<br />
major growth driver. Home automation and home entertainment<br />
together are forecast to grow to over $300 million<br />
per annum by 2017.<br />
“Until quite recently ZigBee/RF4CE has been the lead<br />
choice for interoperable low power wireless connectivity in<br />
the home automation and home entertainment markets,<br />
and one look at the ZigBee Alliance’s website shows the<br />
breadth of equipment suppliers that have developed products<br />
using the technology,” added Cooney. “However, the<br />
introduction of Bluetooth Smart is set to disrupt what<br />
could have been an almost monopoly in the low power connectivity<br />
space,” he said.<br />
Proprietary wireless technology is expected to continue<br />
to dominate many markets for at least the next five years;<br />
however, the market is changing. The move from IR to RF<br />
remote controls and the increasing need for interoperability<br />
between “hub” devices and sensor “nodes” are two main<br />
factors driving growth for standards based low power connectivity<br />
such as ZigBee/RF4CE and Bluetooth Smart.<br />
There will be a battle over the coming years with each<br />
technology finding its own niches. In the longer term lowpower<br />
Wi-Fi could also be a major competitor.<br />
Competition from other technologies will have a major<br />
effect on ZigBee/RF4CE growth in the coming years.<br />
However, the ability to have almost unlimited node counts<br />
within a ZigBee system will help drive growth where other<br />
technologies compete (e.g. large building automation systems).<br />
So, while previously robust industry forecasts might<br />
not be met, Zigbee/RF4CE still has a lot of room to grow.<br />

GaAs Epitaxial Substrate Production<br />
Registers Small Gains<br />
Continuing growth in demand for handset power<br />
amplifiers offset a shift away from GaAs technology for<br />
handset switches in 2011. The result of these two opposing<br />
trends was growth of GaAs epitaxial substrate production<br />
of nearly 3 percent. Despite this small increase in production,<br />
the overall value of the GaAs epitaxial substrate<br />
market grew by 19 percent.<br />
However, Strategy Analytics believes the disruptions<br />
caused by the 2011 earthquake and tsunami in Japan temporarily<br />
increased substrate pricing and this revenue<br />
growth is not sustainable. Strategy Analytics has recently<br />
released a spreadsheet model and Forecast and Outlook<br />
report from their GaAs and Compound Semiconductor<br />
Technologies Service (GaAs) entitled “Markets for Semiinsulating<br />
GaAs Epitaxial Substrate Markets: 2011-2016”.<br />
This report forecasts that total demand for semi-insulating<br />
(SI) GaAs epitaxial substrates from manufacturers such as<br />
IQE, VPEC, Kopin, RFMD, Hitachi Cable, Intelliepi and<br />
Sumitomo reached slightly more than 30382-kilo square<br />
inches (ksi) in 2011. The report estimates that this demand<br />
resulted in nearly $601.5 million in revenues. The forecast<br />
indicates demand will continue to show slow growth,<br />
reaching nearly 35490 ksi by 2016. With disruptions in the<br />
supply chain easing, the report forecasts that substrate<br />
price erosion will return to a more conventional profile and<br />
GaAs epitaxial revenue will decline to $544 million in<br />
2016.<br />
“The small growth in overall GaAs epitaxial substrate<br />
production in 2011 masked two more significant trends,”<br />
noted Eric <strong>High</strong>am, Director of the Strategy Analytics<br />
GaAs and Compound Semiconductor Technologies Service<br />
(GaAs). “MOCVD material production increased sharply,<br />
fueled by growth in HBT-based handset PAs. Nearly offsetting<br />
this growth completely was a sharp decline in production<br />
of wafers using MBE epitaxy.”<br />
Asif Anwar, Director in the Strategy Analytics Strategic<br />
Technologies Practice (STP) added, “The chief use of GaAs<br />
MBE wafers has been for HEMT devices in handset<br />
switching applications but device manufacturers have<br />
been moving away from GaAs for these switches. We<br />
believe the bulk of this technology conversion is complete<br />
and the MBE market will return to slow growth.”<br />

ticketing are all areas in which businesses are looking to<br />
operate in a quicker, smarter, and more secure manner.<br />
Practice director John Devlin said, “Despite the general<br />
economic malaise affecting much of the world, solutions<br />
and technologies that can deliver savings and provide<br />
wider benefit will attract investment. The business model<br />
and use case for RFID is now being better understood and<br />
real-world ROI can be demonstrated in a growing number<br />
of instances.”<br />
The need to be able to improve manufacturing and supply<br />
chain efficiencies, as well as track and identify components,<br />
products, and assets is now being considered in a<br />
growing range of market sectors. The ability to add and<br />
implement greater security is another factor driving the<br />
growing adoption of RFID in both traditional and new<br />
applications.<br />
Devlin added, “There will be an increasing need for<br />
companies and, in particular government organizations,<br />
to be able to track and authenticate their in-house assets<br />
and equipment as well as items and products provided<br />
and sold. Think of the supply of food and pharmaceutical<br />
products, as well as consumer electronics and automotive,<br />
from the farm or point of manufacture and onto consumption<br />
and use. Similarly the installation and maintenance<br />
of large projects, e.g. transportation and utilities, are of<br />
critical importance. We expect to see increasing use of<br />
RFID ahead of alternative solutions to provide this audit<br />
trail.”<br />

RF Feeder Cable Market Analysis<br />
EJL Wireless Research is announcing the second edition<br />
of its global RF feeder cable market analysis titled<br />
“Global BTS Transmission Feeder Cable Analysis and<br />
Forecast, 2012-2016.” The RF feeder cable is the primary<br />
solution that interfaces the traditional tower bottom macro<br />
cell BTS cabinet to the BTS antenna.<br />
“The market dropped 13.6% year over year in total<br />
volumes (measured in km of cables) in 2011.<br />
The 1/2” diameter feeder cable segment replaced the<br />
7/8” diameter segment as the largest in shipment volumes<br />
in 2011 however the 1 1/4” or greater diameter feeder cable<br />
segment remained the largest in revenues in 2011.<br />
Aluminum cable product shipments picked up share overall<br />
in 2011 due to emerging markets demand and higher<br />
copper pricing” said founder and President, Earl Lum.<br />
Weak end market demand in Asia Pacific (China), Latin<br />
America and Africa offset strong demand in India in 2011.<br />
“We estimate a net decline in BTS feeder cable shipments<br />
over the next five years as migration to tower top<br />
RRU BTS site architectures will force the replacement of<br />
coaxial feeder cables with fiber optic cables. We see a<br />
potential growth year in 2013 due to a stronger decline in<br />
2012 than in 2011 as demand is being pushed out. While<br />
RF cables will still be required for the transmission line<br />
connection from the RRU port to the antenna port, the<br />
much shorter lengths will alter the economic viability of<br />
the feeder cable market,” said Lum.<br />

Small Cell Shipments to Reach 8.6<br />
Million Units by 2017<br />
The Strategy Analytics Wireless Operator Strategies<br />
(WOS) report, “Small Cell Market Outlook 2012 – 2017—<br />
Seven Market Opportunities Quantified” predicts that<br />
Public Femto Cells will ship in the greatest volume in 2013<br />
and 2014 until Pico Cells overtake them in 2015. From<br />
2016 Metro Cells are expected to ship over 1 million units<br />
a year while Public Femto Cells will ship over 2 million<br />
and Pico Cells over 3 million.<br />
The report forecasts global shipments by region and<br />
cell type from 2012 to 2017.<br />
“Regionally, Asia Pacific is projected to be the largest<br />
market for small cells with over 12 million shipments<br />
between 2013 and 2017,” commented Guang Yang,<br />
Beijing-based Senior Analyst for Wireless Operator<br />
Strategies. “Over 2 million of the cumulative Asia Pacific<br />
shipments are expected to be Metro Cells, but over 5.5<br />
million will be Pico Cells and another 4.5 million Public<br />
Femto Cells.”<br />
The report further evaluates the market opportunity<br />
for specific applications, presenting not only total shipment<br />
numbers but also forecasts of the Served Available<br />
Market (SAM) for seven Use Cases to enable mobile<br />
operators to match the right type of small cells to specific<br />
requirements. Sue Rudd, Strategy Analytics Director,<br />
Service Provider Analysis, noted “The Use Case requirements<br />
span from overloaded urban ‘Hot Zones’ to Macro<br />
Cells needing range extension to sites with sporadic traffic<br />
peaks like football stadiums.” She adds, “This analysis<br />
will help operators and infrastructure vendors to develop<br />
business plans that optimize small cell technology for<br />
each Use Case over the next 5 years and to penetrate<br />
these huge markets in the decade beyond.”<br />

PDA<br />
Texas Instruments introduced the world’s first programmable<br />
differential amplifiers (PDAs). The 2.4 GHz<br />
LMH6881 single-channel PDA and 2.4 GHz LMH6882<br />
dual-channel PDA provide optimized noise, distortion and<br />
bandwidth performance over a 6 dB to 26 dB gain range,<br />
simplifying the way engineers design with differential<br />
amplifiers. Designing systems with PDAs increases flexibility<br />
and significantly reduces design time, solution size<br />
and bill of materials cost for a broad range of applications.<br />
