The design and performance of a high efficiency Ka-band power amplifier MMIC utilizing a 0.15um high voltage GaAs PHEMT process (HV15) is presented. Experimental continuous wave (CW) in-fixture results for the power amplifier MMIC demonstrate up to 5W of saturated output power and 30% associated power added efficiency at 35GHz.
