Abstract

An overview is given of a simple and low-cost 1.9-GHz, 25-W power amplifier developed using only one prematched 50-mm PHEMT with external matching circuits on a FR-4 PCB. As the output stage integrated with other driver stages and dc control circuits, a complete four-stage power-amplifier subsystem is also demonstrated. When operating at 38.5-dBm output power with π/4-DQPSK signal, the power-amplifier subsystem shows low distortion, with better than 75-dBc ACPR at 600 kHz and 79-dBc ACPR at 900 kHz offset from the center frequency, and is suitable for PHS 500-mW base-station applications.
