mmWave sensor for automotive radar systems, in distribution
Mouser Electronics is now stocking the AWR1843 automotive radar sensor from Texas Instruments. Built with TI’s low-power 45-nm RFCMOS process, the AEC-Q100 qualified AWR1843 ultra-wideband millimeter wave (mmWave)sensor enables high levels of integration in an extremely small form factor in low-power, ultra-accurate radar systems for automotive applications.

The TI AWR1843 is an integrated single-chip frequency-modulated continuous-wave (FMCW) radar sensor capable of operation in the 76- to 81-GHz wave spectrum. TI’s RFCMOS process enables a monolithic implementation of a system with three transmit (TX) and four receive (RX) channels plus built-in phase lock loop (PLL) and analog-to-digital converters (ADCs). The sensor integrates a digital signal processor (DSP) subsystem, based on TI’s C674x DSP, for radar signal processing, as well as a built-in self-test (BIST) processor subsystem responsible for radio configuration, control, and calibration. An onboard user-programmable Arm Cortex-R4F processor enables object tracking and classification, Autosar, and interface control.
