Paper Abstract

A low cost heterodyne receiver assembly has been designed and fabricated for systems such as the U.S. Army's Multiple Launch Rocket System (MLRS). The receiver assembly was fabricated from `commercial off the shelf' (COTS) components, taking advantage of the low cost of volume production for the dewar, detector, and cryogenic cooler. The design and performance of the heterodyne receiver assembly is the subject of the present paper. With minor modifications to the standard `imaging photodiode' process, heterodyne quantum efficiencies of 30% have been demonstrated at 2 GHz. While the performance achieved so far has been encouraging, further improvements in device design and processing technology can serve to enhance the performance. With these changes, we believe that heterodyne quantum efficiencies of 40% with bandwidth exceeding 3 GHz is achievable. These changes are also expected to reduce the cost of fabrication of these photodiodes.
