<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 />
