2.2.1 IWR1642 Single-Chip Radar Solution
The IWR1642 is an integrated single-chip, frequency modulated continuous wave (FMCW) sensor capable
of operation in the 76 to 81 GHz 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 two transmitters with a closed loop PLL for precise and linear
chirp synthesis. 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 5
MHz with reconfigurable output sampling rates. The presence of ARM
®
Cortex
®
R4F and Texas
Instruments C674x DSP (fixed and floating point) along with 1.5 MB of on-chip RAM enables high-level
algorithm development.
