摘要：

A prototype down-converting mixer MMIC based on planar Schottky diodes and a production version based on HEMT diodes are reported. Measurements with a 1-2-GHz i.f. indicate conversion losses of 8-11 and 10-14 dB, respectively, and image rejections > 20 dB. A HEMP-based mixer-amplifier MMIC with conversion gain of 3-8 dB and image rejection > 18 dB is also reported. Simulations agree well with these measurements. Image rejection is produced by an on-chip i.f. coupler. This is the first report, to the authors' knowledge, of fully monolithic, image-reject downconverters of this type.
