Description for the AWR6843
The AWR device is an integrated single chip mmWave sensor based on FMCW radar technology capable of operation in the 60GHz to 64GHz band. It is built with TI’s low power45nm RFCMOS process and enables unprecedented levels of integration in an extremely small form factor. 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.
