In summary, the A121 is a radar system based on pulsed coherent radar (PCR) technology with a footprint of 29 mm². The A121 60GHz radar system is optimized for high precision and low power delivered as a one-package solution with integrated baseband, RF front-end, and antenna-in-package (AiP). This enables easy integration into any portable battery-driven device. The radar remains uncompromised by any natural source of interference, such as noise, dust, color, and direct or indirect light.
