   Abstract:
   A single stage 20-GHz power amplifier was developed using double-doped AlInAs-GaInAs on InP HEMT. Output power of 516 mW (0.645 W/mm) with power-added efficiency of 47.1% with 7.1-dB gain were obtained from an 800-μm wide device. The device had a saturated output power of more than 560 mW (0.7 W/mm). This is believed to be the highest combination of output power, power density, gain, and power-added efficiency reported for an InP-based FET at this frequency.
