IGN1011S25 and IGN1011S25S are high power GaN-on-SiC RF power transistors that have been designed to suit the unique needs of IFF/SSR avionics systems. They operate at both 1030 and 1090 MHz. Under 32μs pulse length, 4% duty cycle pulse conditions, they supply a minimum of 25 W of peak output power, with typically >20 dB of gain. 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.
