A highly integrated silicon platform (Hi-Mission) for high frequency applications is introduced. This platform utilizes heterogeneous Multi-Chip Module-Deposited (MCM-D) technology with integrated passive devices together with silicon and GaAs Monolithic Microwave Integrated Circuit (MMIC) technology developed for the automotive Ultra Wide Band (UWB) radar (short-range radar) frequency band from 77 to 81 GHz. Developments are described in the area of MCM-D process development, MMIC, integrated phased array antenna, module design, and assembly process development. The demonstrator is composed of two test vehicles designed for conducted and radiated measurements, respectively. Test results are presented at the component and module level.
