Production Military Markets for GaN
Electronic Warfare • Uses broadband and high-power microwave emission • Disrupt and jam RF signals used to detonate IEDs
AESA Radar • Arrays rely on hundreds or thousands of T/R modules that can be phase shifted to form
and steer the beam • So many modules place a premium on size, weight, power efficiency and high power
performance
Tactical Radio Communications • “Network-centric” battle philosophy demands agile, broadband communications
channels • Radios may have to operate over a frequency range of 30-3000 MHz at power levels up
to 100W, while accommodating portable, manpack and vehicle mount form factors

Conclusions
• Compound semiconductor technologies have enabled defense systems.
• Future generations of radar, communications and EW systems will continue to drive demand for compound semiconductor capabilities.
• Strategy Analytics forecasts that GaN will become a pivotal technology leveraging high power, wideband and high frequency attributes.
• Military applications will account for more than 2/3 of GaN revenue in 2015
