A 40GHz superheterodyne receiver integrated in 0.13/spl mu/m BiCMOS SiGe:C HBT technology

This paper presents a superheterodyne down-converter realized using SiGe:C BiCMOS HBT. Based on a single-ended architecture, the low noise amplifier (LNA), the fundamental oscillator and the mixer were first characterized separately and finally the down-converter. The down-converter exhibits conversion gain of 13 dB and NF/sub DSB/ of 7 dB, and the associated oscillator performs phase noise of -90 dBc/Hz at 1 MHz from the 40 GHz carrier frequency.
