Abstract :
A state-of-the-art X-band high-efficiency MMIC power amplifier has been demonstrated. An average output power of 3.6 W at an average 41% power-added efficiency over a 40% bandwidth from 7.0 to 10.5 GHz has been achieved. An average power density of 500 mW/mm and peak power density of 550 mW/mm have been measured across this bandwidth. Peak efficiencies of 56% at 7 GHz and above 50% from 7.5 to 9 GHz were achieved when the drain was biased at 6 V.<>
