Abstract :
A state-of-the-art X-band high-efficiency monolithic 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 excellent average power density of 500 mW/mm and peak power density of 550 mW/mm have been measured across this bandwidth.<>
