This paper presents the design and performance of a 200 GHz, sub-harmonically-pumped, heterodyne receiver MMIC realized in 100 nm metamorphic HEMT technology. The lownoise amplifier stage sets the receiver noise figure to 7 dB and, 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...
