  • Abstract
    Millimetre-wave heterojunction bipolar transistor (HBT) amplifiers have been developed for the first time in the form of alumina substrate MIC. These amplifiers were fabricated using AlGaAs/GaAs HBTs having an emitter size of 1*10 mu m2 with a maximum oscillation frequency of 111 GHz. A single-stage amplifier showed a gain of 3.4 dB with a P1dB of 9.6 dBm, and a two-stage amplifier showed a gain of 6.1 dB with a P1dB of 8 dBm at 50 GHz.
