Abstract :
The authors describe the measured cryogenic noise performance of a 0.1- mu m T-gate InP HEMT (high electron mobility transistor) operating at 30 K and a two-stage HEMT low-noise amplifier operating at 19 K. The InP HEMT achieved a noise temperature of 5-15 K when operated at 30 K and at 12-18 GHz, while the noise temperature of the two-stage amplifier decreased from 160 K to 40 K with cryogenic operation at 30-34 GHz.<>
