Summary :

The design and performance of a S-band solid-state power amplifier (SSPA) module are reported. The SSPA module consisted from four MMIC power amplifiers (PA) achieves 90 W output power, 35% power added efficiency (PAE), and 80% power combine efficiency. The MMIC PA achieves over 28 W output power, 25 dB small signal gain, and over 38% PAE. This paper also describes the large-signal circuit design for the MMIC PA using an improved nonlinear FET model developed for high power amplifier applications.
