In this work the design and characterization of an InP/InGaAs single heterojunction bipolar transistor (HBT) W-band amplifier is described. The amplifier achieves 26-dB gain at 98 GHz with a bandwidth of 3.1 GHz. On-wafer S-parameter and gain compression measurements are presented. The goal was to explore high gain HBT-amplifiers around 100 GHz. No comparable HBT amplifier at these frequencies could be found in the literature
