Abstract

This is to report on our development for a full-polarization receiver to detect comic microwave background in 85 to 105 GHz band. Two such receivers have been built and tested, and currently undergoing site-testing on Mauna Loa, Hawaii. Each receiver is a very sensitive coherent detector to operate in 85-105 GHz with full polarization capability. Most of the receiver front-end components, including feed-horn, ortho-mode transducer, and low-noise amplifiers, are located in a cryogenic environment. We have designed a MMIC sub-harmonic pumped mixer, operating at 42 GHz, for signal down-conversion. In order to detect faint polarization signals in microwave background, a wide base-band, 2 to 18 GHz, is specified in the receiver design, and the entire base-band will be correlated. The receiver design details and the lab test results will be described in this report.
