Substrate lens antennas have been successfully applied in combination with quartz thin-film substrates for design of an automotive FMCW radar with beam-scanning capability. A series of 77 GHz radar prototypes based on commercial GaAs components have been fabricated and evaluated. In order to achieve lower manufacturing cost of such radar devices an IC design program for SiGe radar components has been initiated. A VCO-prescaler combination for 24 GHz has been designed and tested. The authors' latest development is a complete 77 GHz radar tranceiver IC designed for a commercial SiGe process with fT = 150 GHz. Transmission line stubs realized on-chip using available metal layers have been employed in order to achieve optimum transistor matching required for operation at f > 1/2 fT.
