RF & Wireless<br />
Small Form Factor Omni<br />
Antenna<br />
RFMW, Ltd. announced design and sales<br />
support for small form factor antenna from<br />
Southwest Antennas. The 1001-202 is a<br />
half-wave dipole, omni antenna for 2.1<br />
to 2.5 GHz applications. Measuring only<br />
4.29 inches in height, it offers 2.15 dBi of<br />
peak gain. The antenna features a tough,<br />
black, G10 fiberglass radome and a blackchrome,<br />
TNC(m), non-rotating, RF connector,<br />
making the antenna ideal for lowvisibility<br />
or tactical applications such as<br />
tactical hand-held radios, body-worn radio<br />
systems, unmanned robotics platforms and<br />
other applications where size and weight are<br />
critical. Capable of handling up to 50 W of<br />
RF power, the 1001-202 antenna has a vertical<br />
elevation beamwidth of 77 degrees.<br />

Millimeter-Wave Removable<br />
End Launch Connectors<br />
Pasternack has just released a new line of<br />
high-speed end launch connectors. These<br />
new removable end launch connectors are<br />
perfect for signal integrity measurements,<br />
coplanar waveguide, chip evaluations,<br />
SERDES, substrate characterization, 25 GbE<br />
and test fixture applications.<br />
Pasternack’s new series of high-speed end<br />
launch connectors is comprised of four<br />
models that provide SWR as low as 1.10:1<br />
and a maximum operating frequency of 40 to<br />
110 GHz. Connector options include 1 mm<br />
end launch (110 GHz), 1.85 mm end launch<br />
(67 GHz), 2.92 mm end launch (40 GHz) and<br />
2.4 mm end launch (50 GHz). These highperformance<br />
end launch connectors don’t<br />
require soldering, are re usable and have a<br />
compact profile with a 0.350 inch mounting<br />
width. They feature an outer conductor<br />
made of stainless steel and a gold-plated<br />
beryllium copper center contact. These<br />
highspeed end launch connectors are ideally<br />
suited for high-speed digital and mmWave<br />
system development.<br />

3 GHz Sector Antennas with<br />
Improved Performance<br />
KP Performance Antennas announced that<br />
it has released new high performance,<br />
3 GHz sector antennas to its portfolio for<br />
use in WISP networks. KP’s expanded line<br />
of 3 GHz sector antennas consists of four<br />
new models including the KP-3SX4-65<br />
quad-port 18 dBi sector, the KP-3S3S-65SA<br />
which features two 3 GHz antennas in one<br />
radome, the KP-3DP65S-45 18 dBi Dual<br />
Polarized sector, and the KP-3DP120S-45<br />
3 GHz sector which is specially designed<br />
for LTE applications.<br />
The unique design of these antennas minimizes<br />
interference by utilizing a 65 degree<br />
gain pattern and ±45 degree slant dual polarization<br />
scheme. They are designed to provide<br />
high gain and maximum coverage and<br />
feature improved front-to-back and pattern<br />
roll off that allows for higher spectral efficiency.<br />
These antennas operate in the popular<br />
frequency range of 3.3 to 3.8 GHz and<br />
deliver SWR from 1.5 to 1.7.<br />

Ultra-Low Power<br />
Transceiver for<br />
Bluetooth 5<br />
In the Internet of Things, numerous<br />
tiny sensor nodes are embedded in our<br />
environment. Reducing the power consumption<br />
and enabling operation at low<br />
supply voltage of IoT radio transceivers<br />
is key to enable reliable multi-year battery<br />
life of the billions of IoT devices<br />
in our environment. Furthermore, new<br />
applications are empowered by reducing<br />
power consumption and supply<br />
voltage, such as leave-behind sensors<br />
or wearables.<br />
Imec, together with Renesas, developed<br />
a fully-integrated, highly energy efficient<br />
BT5 transceiver which showcases<br />
the best RX figure-of-merit (FoM) and<br />
the lowest supply voltage among the<br />
state-of-the-art (0.8 V). A low supply<br />
voltage of 0.8 V is beneficial because<br />
it extends battery life by up to 50%,<br />
reduces the complexity of the power<br />
management unit, and allows the use<br />
of a wider range of energy sources such<br />
as energy harvesters.<br />
The transceiver consists of a novel<br />
phase-tracking RX, a digital TX based<br />
on an all-digital PLL (ADPLL) and a<br />
PHY-layer digital baseband. A hybrid<br />
loop filter enhances interference tolerance,<br />
in conjunction with precise frequency<br />
control enabled by the ADPLL.<br />
The receiver fronted achieves a sensitivity<br />
of -95 dBm, while consuming only<br />
2.3 mW (non-duty-cycled) at 0.8 V.<br />
The transceiver chip is implemented in<br />
40 nm CMOS, with a core area of only<br />
0.8 mm 2 , including on-chip matching.<br />
