Abstract
We report a high conversion gain millimeter-wave monolithic IC (MMIC) quadruple subharmonic mixer adopting a novel cascode harmonic generator for an improved conversion gain. The proposed cascode harmonic generator produces 2.9 dB higher fourth harmonic output powers on the average compared with those of the conventional multiplier. The fabricated mixer shows a high conversion gain of 3.4 dB at a local oscillator (LO) power of 13 dBm. High isolations were obtained the LO-to-intermediate frequency (IF) of -53.6 dB and the LO-to-radio frequency (RF) of -46.2 dB, at a frequency of 14.5 GHz. The conversion gain achieved in this work is the best performance among the millimeter-wave MMIC subharmonic mixers reported to date.
