The lownoise amplifier stage sets the receiver noise figure to 7 dB nd, in combination with the resistive down-conversion mixer, allows for an overall conversion gain of 7 dB at 200 GHz RF frequency. The mixer LO port is driven by a frequency doubler and buffer amplifier stage. We use an integrated LO driver amplifier stage with two parallel cascode amplifiers to achieve the operation of the circuit with as low as -13 dBm LO power provided at 100 GHz, thus making the receiver MMIC suitable for multichannel imaging frontends.enMMICmillimeter-wave heterodyne receivermillimeter-wave subharmonic mixermillimeter wave frequency conversionG-BandMHEMT667conference paper
