A number of W-band high performance and highly integrated MMICs in coplanar technology have been developed for radar and imaging applications. They are (a) 40-50 dB high-gain LNAs, (b) variable gain LNAs with a 70 dB gain control range, (c) wide band LNAs, (d) heterodyne receivers, and (e) FMCW radar sensors. The MMICs differ from the present state of the art through small size (3-8 mm2), coplanar technology, and the extensive use of CASCODE amplifier techniques. A power gain density of more than 10 dB/mm2 is obtained for high-gain amplifiers.
