Abstract
We report wide-band amplifiers using AlInAs/GaInAs transferred-substrate Heterojunction Bipolar Transistors (HBTs). A distributed amplifier exhibits 11.5 dB gain and 80 GHz bandwidth. Lumped amplifiers exhibit 8.2 dB gain with 80 GHz bandwidth and 18 dB gain with 50 GHz bandwidth and 400 GHz gain-bandwidth product, record for a single-stage amplifier.Keywords
