IGN0912LM500 and IGN0912LM500A are high power GaN-on-SiC RF power transistors that have been designed to suit the needs of IFF/SSR avionics systems, military tactical data links, and TACAN/DME systems. They operate over the full instantaneous bandwidth of 960-1220MHz. IGN0912LM500 under ELM Mode S [48x (32μs on, 18μs off), 6.4% Long Term Duty Cycle] pulse conditions and IGN0912LM500A under Link 16 [444x (7μs on, 6μs off), 22.7% Long Term Duty Cycle] pulse conditions both supply a minimum of 500 W of peak output power, with typically >18 dB of gain and 65% efficiency. They operate from a 50 V supply voltage. For optimal thermal efficiency, the transistors are housed in a metal-based package with an epoxy-sealed ceramic lid.
