Texas Instruments IWR6x mmWave 60GHz to 64GHz Sensors
Texas Instruments IWR6x mmWave 60GHz to 64GHz Sensors are integrated single-chip mmWave sensors based on FMCW radar technology capable of operation in the 60GHz to 64GHz band. These devices are built with TI’s low-power 45nm RFCMOS process and enable unprecedented levels of integration in an extremely small form factor. Texas Instruments IWR6x mmWave 60GHz to 64GHz Sensors are ideal for low-power, self-monitored, ultra-accurate radar systems in the industrial space.
