Abstract :
This paper will review the progress of HEMT MMW MMIC technologies developed for radiometer sensor applications at Northrop Grumman Aerospace Systems. Specific HEMT MMIC functions that have been developed for the radiometer front-end include the RF LNA, IF LNA and LO driver power amplifiers. We will report recent advancements in both room temperature and cryogenically operated InP HEMT low noise amplifiers and power amplifiers that have reached above 300 GHz for the first time.
