Abstract
Cryogenic characterization of a monolithic W-band pseudomorphic InGaAs HEMT amplifier has been demonstrated for the first time using the picosecond optoelectronic technique. Low temperature, millimeter-wave measurements have been performed without the use of conventional millimeter-wave sources, components, and transitions. At 94 GHz, the single-stage amplifier exhibits gain of 4.5 dB at 300 K, which increases to 7 dB at 70 K.
