5-GHz SiGe HBT monolithic radio transceiver with tunable filtering
2000
IEEE transactions on microwave theory and techniques
A wide-band CDMA-compliant fully integrated 5-GHz radio transceiver was realized in SiGe heterojunction-bipolar-transistor technology with on-chip tunable voltage controlled oscillator (VCO) tracking filters. It allows for wide-band modulation schemes with bandwidth up to 20 MHz. The receiver has a single-ended single-sideband noise figure of 5.9 dB, more than 40 dB on-chip image rejection, an input compression point of 22 dBm, and larger than 70 dB local-oscillator-RF isolation.
