Abstract
Cryogenic receiver modules for 90 and 140 GHz have been developed that are part of an airborne imaging system. They consist of Schottky-barrier mixers followed by GaAs-FET IF amplifiers. The DSB receiver noise temperatures are 210 K for the 90-GW and 250 K for the 140-GHz system. The instantaneous bandwidth is 2.5 GHz for both front ends. Results of some flight tests are presented.Keywords
