A high-performance 85-119 GHz GCPW MMIC low noise amplifier

In this paper, a high-performance four-stage MMIC low noise amplifier based on InP HEMT and grounded CPW (GCPW) technology is presented. The LNA exhibits a measured gain of 20/spl plusmn/3 dB from 85 to 119 GHz, a 33% bandwidth. The noise figure is 3.7 dB at 93 GHz. The measured amplifier P/sub 1 dB/ is 10 mW at 98 GHz.
