Abstract

Five versions of monolithic W-band 0.1 μm AlGaAs-InGaAs-GaAs pseudomorphic HEMT, four-stage, low noise amplifiers based on two different designs were developed. These millimeter wave monolithic integrated circuits have produced a minimum noise figure of 3.5 dB with 23.0 dB gain at 92 GHz and a maximum gain of 33.5 dB with a 6.2 dB noise figure at 102 GHz. This is the highest gain yet reported for a single chip W-band amplifier. The chips feature coplanar waveguide circuit elements and compact size for low-cost production, single-polarity bias requirement, and a minimum of DC bonding pads
