California-headquartered auto-tech provider indie Semiconductor has acquired Silicon Radar, a German company specializing in advanced, highly integrated, high-frequency system-on-chips (SoCs) for automotive radar applications.
The radar industry is transitioning to 120GHz for in-cabin sensing, and to 140GHz for external sensing. These higher frequencies enable the use of antenna-on-chip techniques, greatly raising the integration levels. This enables indie to create products with a complete radar on a chip to expand into new market areas.
Specifically, operation at 120GHz or above enables antennas to be integrated in package or on-die, simplifying the PCB design and dramatically reducing cost especially for in-cabin occupant monitoring systems, where industrial design often cannot allow external antennas optimized for RF performance at lower frequencies.
