Abstract :
A two-stage single-chip X-band power amplifier having an average of 8-W of pulsed output power at 33% duty cycle with 35% power-added efficiency over a 24% bandwidth has been demonstrated. The design achieves increased power and efficiency through the use of a newly developed AlGaAs/GaAs heterojunction FET pulse-doped material structure and incorporation of an off-chip matching network topology that reduces losses.<>
