Abstract :
We report the packaging and first measurement of Indium Phosphide (InP) monolithic microwave integrated circuit (MMIC) low noise amplifiers (LNAs) operating at cryogenic temperatures above 140 GHz. The amplifiers were measured from 160 to 188 GHz at 20 K and tested for noise temperature and gain, with noise temperatures of 160 K. The packaging method and test setup are described, as well as detailed results at room and cryogenic temperatures.
