Abstract

It has been commonly accepted that common-base (CB) HBTs are more suitable for millimeter-wave power amplifier than common-emitter HBTs due to their superior gain. However, the essential gain behavior of CB HBTs is not well understood in detail, and thus the factors limiting their mm-wave performance are not yet clarified. In this work, basic design guidelines of CB HBTs are presented based on a detailed gain performance analysis. In particular, we stress the importance of improving the fT at high collector voltages and reducing the feedback component of wire parasitic capacitance. The analysis is in good agreement with the measured RF performance of the fabricated HBTs.
