Abstract

We report W-band GaN MMIC´s that produce 96% more power at a frequency of 88 GHz in continuous wave (CW) operation than the highest power reported in this frequency band for the best competing solid state technology, the InP HEMT. W-band power module containing a single three stage GaN MMIC chip with 600 μm wide output stage produced over 842 mW of output power in CW-mode, with associated PAE of 14.7% and associated power gain of 9.3 dB. This performance was measured at MMIC drain bias of 14 V.
