Autonomous driving vehicles and automotive RADARs have come to revolutionize our commuting, add quality time to our daily time-schedule that is now wasted in traffic, and increase safety dramatically. Their V2V (Vehicle-to-Vehicle) communication, anti-collision features and pedestrian detection, all contribute to minimizing the risks of a road accident.

In order to achieve the above, high performance RADAR sensors are required, that are based on precise, linear and fast modulators for signal generation and high dynamic range receiver arrays for clean signal reception.

Synthesizers must synthesize precise, repeatable, fast and linear frequency chirps for maximum resolution.

High quality RADARs require multiple TX channels to support diverse transmit antennas.

Multiple Receivers  are needed to enable accurate angle-of-arrival measurements.

And, state of the art silicon processes have to be used for the design of high-end RADARs for commercial use.

Weasic’s FMCW Modulators achieve wide modulation range, maintain constant loop bandwidth and are able to produce the fastest (<2usec) and most linear (<0.1% INL) performance with the lower retrace times.

Our accurate phase shifters enable the combination of multiple transmit signals to form directed beams for long range detection.

Weasic’s receiver arrays with high dynamic range low power dissipation, smart filtering and accurate gain control, allow the accurate undistorted signal reception at the smallest silicon die area.
