77 GHz RADAR  

77 GHz radars enhances automotive safety by enabling vehicles to identify dangerous situations and prevent crashes. They are used to detect different kinds of obstacles such as other vehicles and pedestrians in the 30 to 250 meters range, even in low visibility conditions.

The information provided by the radars is used in ADAS system responsible for multiple applications including autonomous emergency braking and adaptive cruise control.

STRADA770 transceiver, covering the millimeter wave (mmWave) frequency band from 76 to 81 GHz, is designed to provide an optimized solution for high-end ADAS systems. It includes 3 transmitters, 4 receivers and a chirp modulator.

An evaluation kit for developers is available with a STRADA770 evaluation board (EVB-STRADA770) and GUI for programming the IC from a PC using a USB interface.
