Abstract

In this study, we inserted an In0.45Ga0.55As pseudomorphic channel inside the wide bandgap In0.3Al0.7As layer on GaAs substrates to improve carrier confinement and device microwave power performance, as compared with the In0.3Ga0.7As lattice matched ones. The rf output power and power-added efficiency increases from 498 mW/mm to 610 mW/mm, and 37% to 43% under a 2.4 GHz operation for a 1-μm gatelength device.
