Title of Paper: MMIC Based Receivers for Millimeter Wave Atmospheric Sounding

Principal Author: Dr. Todd Gaier

Abstract: We have developed a series of millimeter wave monolithic integrated circuits (MMICs) and MMIC based receiver modules for use in atmospheric temperature and humidity sounders. The heterodyne receivers are designed to cover the frequency range 100-140 GHz and 170-210 GHz and incorporate MMIC low noise amplifiers, mixers, broadband intermediate frequency (IF) amplifiers and local oscillator (LO) drivers. The lower frequency receiver has an average noise of 7.25 dB from 100-125 GHz.
