Integrated circuit technology options for RFICs-present status andfuture directions

摘要

This paper will summarize the technology tradeoffs that areninvolved in the implementation of radio frequency integrated circuitsnfor wireless communications. Radio transceiver circuits have a verynbroad range of requirements-including noise figure, linearity, gain,nphase noise, and power dissipation. The advantages and disadvantages ofneach of the competing technologies-Si CMOS and bipolar junctionntransistors (BJTs), Si/SiGe HBTs and GaAs MESFETs, PHEMTS and HBTs willnbe examined in light of these requirements
