MMICs for next generation radar

The rapid progress towards 5G wireless systems is accelerating the development of mm-wave semiconductor processes, broadband circuits, and system technologies. Similarly, next-generation radar is being expanded and redefined. Legacy radar systems are nearing the end of their life cycle and systems developers are aiming to upgrade their capability while reducing cost, size, and weight. Radar systems have requirements that result in technical circuit design challenges including high power, broadband, and low distortion. This paper focuses on MMIC design challenges specific to the design of next-generation radars that will operate in a crowded wireless environment, allow spectrum sharing, and dynamic frequency selection. Simulated and measured data are presented.
