Abstract

The planar and recessed gate devices were fabricated and compared for their linearity characteristics. AlGaN/GaN heterostructures were formed using a 290 Å thick Al 0.22Ga0.78N barrier layer on sapphire substrate. Gate recessing has been proven to be a viable solution to improve device linearity characteristics. It is observed that further optimization of gate recessing may results in higher efficiency operation while maintaining low distortion level.
