Abstract:
Summary form only given, as follows. A Ku-band 60 W GaN power amplifier is presented. To obtain the high efficiency, new matching circuit topology to control the reflection phase at the 2nd harmonic frequency (2fo) is applied to the power amplifier. The measured power added efficiency (PAE) of 44.9% with the output power of 47.9 dBm (62.2W) is obtained in the 15GHz-band. To the best of our knowledge, the PAE is the highest of the Ku-band GaN power amplifiers reported to date.
