Description

The AWR device is an integrated single chip mmWave sensor based on FMCW radar technology capable of operation in the 60-GHz to 64-GHz band. It is built with TI’s low power45-nm RFCMOS process and enables unprecedented levels of integration in an extremely small formfactor. This is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the automotive space. Multiple automotive qualified variants are currently available including Functional Safety-Compliant devices and non-functional safety devices.
