Abstract :
The design and performance of a 0.15-um PHEMT high efficiency Ka-band power amplifier MMIC is presented. The 3-stage amplifier utilizes a commercially available production released process with demonstrated reliability and 3-metal interconnect (3MI) technology. Experimental continuous wave (CW) in-fixture results for the power amplifier MMIC demonstrate up to 3.8W of saturated output power and 36% associated power added efficiency at 34GHz.
