A 5 GHz RFIC single chip solution in GaInP/GaAs HBT technology

Abstract

Several high performance GaInP/GaAs heterojunction bipolar transistor (HBT) radio frequency integrated circuits (RFIC) implemented by our research group are reviewed in this article. These demonstrated RFICs include source inductively degenerated cascode low noise amplifiers with inter-stage matching, shunt-series shunt-shunt dual-feedback wideband amplifiers, a broadband Gilbert down-conversion micromixer, Gilbert down-conversion mixers with polyphase filters for image rejection, a dual-conversion Weaver receiver, Gilbert up-conversion mixers with output LC current mirror and quadrature VCOs.
