Abstract

This paper discusses the design and measurement of highly efficient GaN HEMT based power amplifier at L Band. Large signal parameters including PAE and power output are presented at an operating frequency of 1 GHz. High efficiency >82 % is achieved by terminating the harmonics at the input as well as at the output and a high output power of 5.2 W is achieved by impedance matching or tuning technique.
