Automotive?mmWave?sensors

Highly precise automotive radar sensors for analyzing dynamic operating conditions

AWRx device architecture goes beyond the RF/analog subsystem, integrating a radio processor and master subsystems, offering customers access to a robust portfolio of AWRx devices scaling from high performance radar front-end to ultra-high resolution, low power and small single chip radar.

Highly accurate

Less than 5 cm resolution accuracy, range detection to hundreds of meters and velocity of up to 300 Km/h.

Versatile intelligence

Detect changing operating conditions and adapt to dynamic driving scenarios on the fly.

Shrink your design

CMOS single-chip sensor integrating best-in-class DSP and MCU in automotive friendly package.

Technology?differentiation

Built with low-power 45nm RFCMOS technology, the AWRx portfolio enables unprecedented levels of integration into a small, automotive-friendly? package. The closed-loop PLL? delivers ultra-high resolution (4cm) with a precise (0.001%) and linear chirp synthesis, offering 4GHz of single-sweep RF bandwidth.

Features of AWR devices include:

Built-in radio processor for intelligent self-monitoring and calibration.
15MHz of IF bandwidth leading to less ambiguity with detection.
300km/h max relative velocity detection.
Built-in cascade functionality delivering less than 1° angular accuracy.
