The mmWave Sensor is an integrated single-chip, frequency modulated continuous wave (FMCW) sensor capable of operation in the 76-81GHz (AWR1843) or 60-64GHz (xWR6843) frequency band. The device is built with TI’s low-power, 45-nm RFCMOS processor and enables unprecedented levels of analog and digital integration in an extremely small form factor. The device has four receivers and three transmitters with a closed-loop phase-locked loop (PLL) for precise and linear chirp synthesis. e

The sensor includes a built-in radio processor (BIST) for RF calibration and safety monitoring. Based on complex baseband architecture, the sensor device supports an IF bandwidth of 10 MHz with reconfigurable output sampling rates. The presence of ARM® Cortex® R4F and Texas Instruments C674x Digital Signal Processor (DSP) (fixed and floating point) along with 2MB (AWR1843) / 1.7MB (xWR6843) of on-chip RAM enables high-level algorithm development. This device is ASIL-B (automotive) or SIL-2 (industrial) targeted and an ideal solution for low power, self-monitored, ultra-accurate radar systems in the automotive space.
