Abstract

This paper describes the development of a millimetre-wave front-end for a 76.5GHz Collision Warning Avoidance (CW/A) car radar. This CW/A sensor is based on a FMCW concept. The main development steps are described and have led to the definition of a fully MMIC-based front-end. Based on a demonstrator done in AWARE a new chip-set has been defined, fabricated and characterised within LOCOMOTIVE. Using a total chip-set area of 13.7 mm2, the first obtained results show a high level of performance.
