Abstract

A low power two-stage InP HEMT MMIC amplifier has been developed. The amplifier utilizes 0.12 µm T-gate InP HEMTs with 225 µm gate periphery. This compact microstrip MMIC is only 1.5 mm 2 in size. It exhibits gain of 12.51 dB at 15 mW of dissipated power over an operating range from 1 to 50 GHz. The gain bandwidth/dissipation figure of merit is 40 dB GHz/mW. The average noise figure is 3 to 3.8 dB over the Ka band.
