A 5.1-5.8 GHz low-power image-reject downconverter in SiGe technology

A 5.1-5.8 GHz downconverter realizes over 36 dB of image rejection while dissipating 24 mW from a 0.9 V supply, or 18.5 mW at 1.8 V. Conversion gain is 14 dB, IIP3=-5.5 dBm and SSB noise figure (50/spl Omega/) is 6.8 dB at 0.9 V. The circuit is realized in a 0.5 /spl mu/m SiGe bipolar technology.
