4-18 GHz AIGaN/GaN Based Distributed Power Amplifier MMIC

A broadband power amplifier MMIC based on AIGaN/GaN HEMT technology from 4 GHz to 18 GHz was designed, fabricated and measured. Potential applications for this type of power amplifier are mainly electronic warfare (EW) and communication systems. Output power levels of more than 2 W are measured, with associated PAE levels of 14 to 25 %.
