Personal communication systems operating at 1.9 GHz require high-efficiency power amplifiers (PAs) operating at 3 V or below. Results on GaAs PAs constructed in a module and an MMIC (monolithic microwave integrated circuit) format are presented. These PAs operate at 3 V with 30 dB gain, 28 dBm output power, and 50% efficiency.<
