380M ADAS Radar

Infineon is sampling its RASIC CTRX8191F 28nm radar MMIC for ADAS. The device detects road users and vehicles at a distance of up to 380 meters, using system configurations with eight transmitters and eight receivers.

The RASIC MMIC enables cascading of multiple devices at low frequencies, reducing the need for expensive RF materials on the circuit board. In addition, the CTRX8191F features an optimised launcher-on-package design that facilitates the use of low-cost waveguide antennas. Its digital PLL offers flexibility in generating complex waveforms with <1 µs flyback time.

Infineon offers a  radar development kit called CARKIT to facilitate the design and deployment of radar systems. CARKIT is based on the CTRX8191F sensor prototyping module, which supports various system configurations, including the transmission of raw ADC data, FFT intermediate results or radar detections via a Gigabit Ethernet interface.

The included example code and graphical user interface enable  prototyping and design. Included is a waveguide antenna that can be replaced with a custom antenna to meet specific customer requirements.

Several versions of CARKIT are already available, including a next-generation 4D front radar configuration with eight transmitters and eight receivers, and a cost-effective corner/front radar solution for the standard market with four transmitters and four receivers,
