Abstract :
We report a 40 GHz MMIC power amplifier in InP DHBT technology that exhibits 14 dBm output power at 1 dB gain compression and 17 dBm saturated output power with 4 dB associated gain. The small-signal power gain is 6.8 dB, the input return loss is less than -20 dB and the output return loss is less than -6 dB. The peak power added efficiency is 12.5%.
