Description
The AWR6843 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. The AWR6843 is an ideal
solution for low power, self-monitored, ultra-accurate radar systems in the automotive space.
