A 94-GHZ 0.35-W POWER-AMPLIFIER MODULE

This paper presents a 94-GHz power amplifier (PA) module, This module contains three identical monolithic microwave integrated circuit (MMIC ) PA chips and demonstrates 0.35-W output power at the waveguide outpu t port with a miniature size, The MMIC PA. is a two-stage monolithic W -band PA using 0.1-mu m pseudomorphic AlGaAs/InGaAs/GaAs T-gate power high electron mobility transistor (HEMT) process, This MMIC PA exhibit s a measured linear gain of 8 dB and a maximum output power of 300 mW with 10.5% peak power-added efficiency (PAE) at 94 GHz, To our knowled ge, both the 300-mW output power MMIC PA and the 0.35-W PA module repr esent the highest output power amplification component performance at this frequency.
