<strong>MILITARY</strong> <strong>AND</strong><br />
<strong>AEROSPACE</strong><br />
<strong>SOLUTIONS</strong> <strong>GUIDE</strong>
Military and Aerospace electronics systems continue<br />
to demand increasing performance and throughput<br />
at the highest frequencies. These demands, together<br />
with stringent limitations on power consumption,<br />
size, weight, and of course, cost, are accelerating the<br />
adoption of new digital architectures for signal<br />
acquisition and generation.<br />
<strong>Inphi</strong> solutions are powering next-generation Military<br />
and Aerospace systems with advanced digital<br />
architectures that simplify expensive, power hungry<br />
RF front ends. <strong>Inphi</strong> offers the most complete<br />
portfolio of high performance digital, analog, and<br />
mixed signal products for designs from DC to 50 GHz.<br />

Monobit Receiver<br />
In conventional Electronic Warfare (EW) or<br />
Electronic Countermeasure (ECM) systems,<br />
Instantaneous Frequency Measurement (IFM)<br />
receivers measure the frequency of a radar pulse<br />
in real time. However, due to the architectures<br />
of these systems, it is difficult to measure two<br />
simultaneous frequencies.<br />
Monobit Receivers were developed to address this problem. A<br />
monobit receiver is a single-bit analog to digital converter, plus<br />
advanced digital signal processing (DSP) algorithms to extract the<br />
frequency and phase information. A key enabling technology for<br />
monobit receivers is the monobit analog-to-digital converter<br />
(ADC), as it determines the maximum input signal frequency and<br />
measurement bandwidth.<br />
The advantages of monobit receivers vs.<br />
IFM receivers include:<br />
Measurement of simultaneous frequencies<br />
Smaller size and lighter weight<br />
Lower cost and power<br />

Direct Conversion Receiver<br />
A traditional receiver uses multiple IF stages, with mixers,<br />
local oscillators (LOs), filters, etc. <strong>Inphi</strong>’s high bandwidth<br />
Track and Hold Amplifiers (THA), with input analog<br />
bandwidth of up to 18 GHz, enable direct conversion<br />
receiver architectures by extending the input analog<br />
bandwidth of commercially available ADCs. This results in<br />
systems with less lower power, smaller size, and lower cost.<br />
<strong>Inphi</strong> offers the highest performance, commercially<br />
available Track and Hold Amplifiers in the industry.<br />

Digital Spectrometer<br />
The next generation of radio telescopes, with large arrays of smaller antennas, is driving much higher computational<br />
and interconnect bandwidths. However, traditional radio astronomy instrumentation is highly customized for<br />
software to perform analyses such as beam forming and wide band spectroscopy.<br />
An essential element of these systems is a high speed digital spectrometer that directly digitizes the downconverted IF<br />
enables these next generation digital spectrometers to operate with higher bandwidth, higher resolution, lower<br />
power, and lower cost.<br />

Phase Locked Loop<br />
Phase locked loops (PLL) are used for many high<br />
speed communications applications such as<br />
frequency synthesizers, clock and data recovery,<br />
and frequency multipliers. In the highest<br />
performance applications, discrete prescalers<br />
(frequency dividers) are used to support<br />
frequencies beyond the range of integrated<br />
PLL chips.<br />
<strong>Inphi</strong>’s prescalers offer the highest frequency range,<br />
lowest phase noise, lowest power, and highest input<br />
sensitivity. They include:<br />
25671DV DC to 25 GHz Divide-by-2 Prescaler<br />
