Abstract

This contribution reports the design of an X-band MMIC power amplifier in a 0.25 um GaN technology, proposing for the first time a harmonic manipulation approach on a class C bias condition. Output network provides the power matching condition at fundamental frequency and an open circuit condition at the 3rd harmonic; the correct phase ratio between drain current components is assured by the proper input 2nd harmonic impedance. This solution allows to reach an efficiency higher than 60% in the frequency band 8.5 GHz–9.5 GHz.
