Abstract :
We report three-stage monolithic amplifiers for the 140-220 GHz frequency band. Two designs have been fabricated in an InAlAs/InGaAs transferred-substrate HBT technology. The first design exhibited a small-signal gain of 12.0 dB at 170 GHz, and the second design exhibited a gain of 8.5 dB at 195 GHz.
