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.
