Airborne Imaging System using Cryogenic Receiver Modules at 90 and 140 GHz
A high-resolution airborne imaging system has been developed that uses cryogenic receiver modules at 90 and 140 GHz. They consist of Schottky-barrier mixers followed by GaAs-FET IF amplifiers. The DSB receiver noise temperatures are 210 K for the 90 GHz 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.
