S3KM111L 24 GHz mmWave Radar SOC
●General Description
■The S3KM111L is an integrated single-chip mmWave sensor SoC based on FMCW radar transceiver technology. It works in the 24 GHz K-band with up to 1 GHz modulation bandwidth in every single frequency sweeping chirp.
■The S3KM111L offers a low-cost fully integrated solution for all critical mmWave functions with full transceiver and signal processing path, including full K-band RF transceiver, on-chip pattern generator, PLL, and ADC. The pattern generator supports multiple frequency sweeping modes with different time-frequency waveforms, e.g. saw-tooth and triangular waveforms. The pattern generator and PLL support fast chirp mode up to 8 kHz chirp rate. The digitized signals from the receiver chain can be serialized via multiple output interfaces.
■The device is packaged in a 32 pin 4 mm x 4 mm leadless ROHS compliant QFN package for easy interfacing to a wide range of antenna board technologies.
