A single module compact efficient harmonic tuned 160 W power amplifier for GPS application

Abstract

This paper presents the design of a hybrid harmonic tuned solid state power amplifier (SSPA) for global positioning system (GPS) application. The SSPA provides peak output power of 160 W, with power added efficiency (PAE) of 61%, based on a single packaged device from Sumitomo. The targeted power and PAE are obtained by properly tuning the source/load impedance at second and third harmonics also. The realized SSPA is characterized over a bandwidth of 50 MHz in L-band (fc=1.575 GHz).
