Abstract :
In this paper we present a 60GHz-band high-gain MMIC cascode amplifier with InGaP/GaAs HBTs. The cascode configuration which consists of a common-emitter HBT followed by a common-base HBT, and a virtual grounding technique using open-ended stubs is adopted to achieve a high-gain and small-size amplifier. The fabricated MMIC cascode HBT amplifier with 1.2mm/spl times/1.3mm size shows a gain of 20dB in the 60GHz-band.
