Influence of recess extension on double heterostructure metamorphic HEMT for power application at 60 GHz (2002)

Abstract
This paper presents the influence of the recess extension on the power performance of double heterostructure Al0.65In0.35As/In0.35Ga0.65As/GaAs metamorphic HEMT’s in the millimeter wave range. Depending on the recess extension, devices exhibit an extrinsic cut-off frequency varying from 80 to 120 GHz. Output power measured at 60GHz with passive load pull bench can reach a power density of 340mW/mm with 6.5 dB linear gain and 21%PAE.
