Abstract
An InP MMIC process was developed and optimized for ultra-low noise amplifiers (LNAs) operating at cryogenic temperature. The amplifiers from the process are working up to 100 GHz. The processed wafers are 4" and can carry more than 4000 3-stage units. For a significant number of 6-20 GHz 3-stage LNAs we have measured an average noise temperature of 5.8 K at ambient temperature of 10 K, state of the art in this frequency range, and 66.3 K at 300K. Associated gain was 35.9 dB (10K) and 33.2 dB (300 K). The standard deviation at room temperature for 47 LNAs was 1.5 K for the noise and 0.3 dB for the gain.
