A compact V-band 3DMMIC single-chip down-converter using photosensitive BCB dielectric film

摘要

A high-density MMIC V-band down-converter that employs the masterslice 3DMMIC technology and photosensitive BCB dielectric film, is presented. The down-converter is structured using an 8/spl times/2 master array in a 1.84 mm/spl times/0.87 mm chip. A down-converter MMIC with H-MESFET with f/sub max/ of 130 GHz demonstrates the gain of 19.3 dB and image rejection ratio of above 18 dB over the frequency range of 56.5 GHz to 59.5 GHz; its associated gain-density is five times higher than that of conventional MMICs.
