A fully passivated ultra low noise W-band monolithic InGaAs/InAlAs/InP HEMT amplifier

Abstract

A W-band 3-stage monolithic low noise amplifier has been developed based on InGaAs/InAlAs/InP HEMT MMIC technology. Both wafer passivation and stabilization bakes have been introduced for the first time to the MMIC process to make it more suitable for production. A minimum noise figure of 3.3 dB and 20 dB associated gain has been achieved at 94 GHz and represents the best reported performance to date for any passivated multi-stage MMIC LNA's operating at W-band.<>
