Bandwidth is king in aerospace and defense applications - Story
January 29, 2016
Wider frequency communication bands require not only a larger observed bandwidth from a system analog-to-digital converter (ADC), but can also push the need for a higher full-power bandwidth. In some applications, such as electronic warfare (EW) and active phased-array radar, this can require the use of a higher order Nyquist rate band. Next-generation gigasamples per second (GSPS) ADCs allow GHz sampling well into the 3rd and 4th Nyquist band with decimation options to get the dynamic range benefits of oversampling. If an ADC's input bandwidth is high enough, it is possible to downconvert directly in the ADC by undersampling the infrared (IF) signal of interest. Higher-bandwidth input signals and sample rates enable direct RF sampling of wider band signals and possible reduction of an entire stage in a signal chain for lower system power and simplicity.

SWaP: The RF solution that can mean the difference between flying high and being grounded - Story
October 07, 2015
Defense and commercial airborne platforms differ in many ways: Defense platforms focus on multifunction systems and power management for mission-critical functions such as electronic warfare, fire control, radar, etc., while commercial aircraft place high emphasis on safety and system redundancy. One area of common concern for both is maximizing payload efficiency. Every ounce of weight, cubic centimeter of space, and milliwatt hour of power is carefully planned, as both focus on balancing size, weight and power (SWaP). Advances in RF technology can provide a leapfrog advantage for manned and unmanned aircraft in both markets.

RF & microwave innovation drives military radar and electronic warfare applications - Story
September 01, 2015
In this Q & A with Bryan Goldstein, General Manager of the Aerospace and Defense business unit at Analog Devices, he discusses how innovations such as Gallium Nitride (GaN) technology is driving the radio frequency (RF) and microwave market and, in turn, radar and electronic warfare designs. He also comments on the?evolution in defense procurement. Edited excerpts follow.

Multiband military communications challenges overcome by software-defined radio - Story
October 03, 2014
The ability to access accurate, real-time information across secure data links is a cornerstone of any successful military campaign. This ability is especially needed today given the requirement of the command-and-control center to communicate directly and instantly with soldiers in the field via both voice and data. What should be a strategic and tactical advantage, however, is only as good as the ability of advanced wireless technology to navigate a web of complex radio frequency (RF) and signal-processing technologies and to render a seamless, reliable, and secure communications network that delivers the right information at the right time in an ever-more-challenged RF spectrum.
