IWR6843 - Texas Instruments

IWR6843 Single-Chip 60 to 64-GHz mmWave Sensor

The IWR6x43 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 power 45-nm RFCMOS process and enables unprecedented levels of integration in an extremely small form factor. This device is an ideal solution for low power, self-monitored, ultra-accurate .
