Texas Instruments IWR1642 76-81GHz mmWave Sensors
Texas Instruments IWR1642 76-81GHz mmWave Sensor is an integrated single-chip mmWave sensor based on FMCW radar technology capable of operation in the 76 to 81GHz band with up to 4GHz continuous chirp. The device is built with TI’s low-power 45nm RFCMOS process, and this solution enables unprecedented levels of integration in an extremely small form factor. The IWR1642 is an ideal solution for low-power, self-monitored, ultra-accurate radar systems in the industrial applications such as building automation, factory automation, drones, material handling, traffic monitoring, and surveillance.
The IWR1642 includes a monolithic implementation of a 2TX, 4RX system with built-in PLL and A2D converters. This sensor also integrates a DSP subsystem, which contains TI's high-performance C674x DSP for the RF signal processing. The device includes an ARM R4F-based processor subsystem, which is responsible for front-end configuration, control, and calibration. Simple programming model changes can enable a wide variety of sensor implementation with the possibility of dynamic reconfiguration for implementing a multimode sensor.
