Linearized GaN SSPA

This linearized solid-state RF power amplifier operates from 17.7 to 20.2 GHz and delivers saturated output power of 10 W with a gain of 45 dB and efficiency of more than 30%. It integrates a thin-film amplifier, attenuator, equalizer, linearizer, and control circuits. The SSPA has an integrated amplitude and phase pre-distortion generator, requires -5 V/+5.5 VDC/+24 VDC, consumes less than 32.5 W, and is available in a hermetic enclosure with 2.92 mm connectors.
