In this work, a 140 GHz down-conversion mixer has been developed based on SiGe BiCMOS technology. The mixer employs a G m-boosting method intended for simultaneous achievement of improved conversion gain and reduced LO power requirement. Measured peak conversion gain is 7.4 dB at RF frequency of 135.6 GHz and LO power of 10 dBm at 134 GHz. The entire circuit draws 0.67 mA from a 2.2 V supply. Measured input referred P -1dB is -21 dBm.
