50 to 70 GHz InP/InGaAs HBT amplifier with 20 dB gain

In this paper the design and a complete characterization of an InP/InGaAs single heterojunction bipolar (SHBT) mm-wave amplifier is described. The circuit is designed for the 60 GHz band allocated for wireless LAN and mobile communications. The amplifier achieves a gain of 20 dB from 50 GHz to 70 GHz. Beside S-parameter noise and gain compression measurements are presented. No comparable HBT amplifier at 60 GHz could be found in literature.
