A 3.5 watt high efficiency GaAs FET amplifier for digital telephone communications

A high-efficiency 3.5-W power module intended for commercial application in the digital cellular telephone market is described. The demonstration circuit is designed to be coupled with a functional gain control circuit or can be a stand-alone power stage. The GaAs FET module operates at 6.2 V, and produces 35.5 dBm of output power, 12.5 dB of gain, and 53% power added efficiency in the 890-920-MHz frequency range.<>
