Low noise wideband fiberoptic MMIC-based receiver

Abstract

A low-noise, wideband, fiber-optic monolithic-microwave-integrated-circuit (MMIC)-based receiver consisting of a two-stage feedback amplifier with minimum gain of 10 dB and 5 dB maximum noise figure from 6 to 15 Hz is presented. This bandwidth and noise performance represent a significant improvement over available hybrid designs. The receiver is usable up to 17 GHz. The improved RF performance is obtained by flip-chip mounting a photodiode onto the MMIC chip, which minimizes the parasitics. thereby extending bandwidth and improving noise.<>
