  • Abstract
    Broadband amplifiers with AlInAs/GaInAs transferred-substrate heterojunction bipolar transistors (HBTs) are described. A simple Darlington configuration with resistive feedback has 50 GHz 3 dB bandwidth and 10 dB gain. This high bandwidth results from the high device bandwidth of transferred-substrate HBTs fabricated in an IC process
