• 論文の詳細を見る

• We present a 94 GHz monolithic down-converter that consists of a two-stage amplifier and a single-balanced mixer using the 0.1-μm metamorphic high electron mobility transistor (MHEMT) technology. The two-stage amplifier (30 μm×2) has a gain of 8.5 dB at 94 GHz. The single-balanced mixer with two Schottky diodes (20 μm×2) and the high-directivity tandem coupler exhibits the conversion loss less than 9.5 dB. The down-converter of a 3.3 × 2.5 mm^2 chip size shows a low conversion loss of 〜2 dB at 94 GHz and excellent LO-to-RF isolation above 35 dB in a frequency of 90-98 GHz.
