In this article, we fabricated a 94 GHz monolithic down-converter that consists of a two-stage amplifier and a single-balanced mixer using the 0.1-mu m metamorphic high electron mobility transistor (MHEMT) technology. The down-converter of a 3.3 x 2.5 mm(2) chip size shows a low conversion loss of similar to 2.8 dB at 94 GHz and excellent LO-to-RF isolation above 35 dB in a frequency of 90-98 GHz. Also. we fabricated the millimeter-wave (MMW) module that exhibits a conversion loss of 7-8.5 dB from 93.66 to 94.365 GHz.
