60GHz 2D Detection model SC1221AR3



SC1221AR3 is a low power CMOS 60GHz radar sensor device and available for 2D location sensing.


  • ●Suited for 2D motion sensing

    • 1 x 4 uniform linear array Rx antennas detect azimuth angle, velocity and distance of multiple objects
    • High-accuracy linear chirp FMCW radar
    • Sensing area example: up to 10m(*1), 120 degree(*1) angular width
  • ●Highly integrated device enabling easy hardware design

    • Integrating antennas, radio, ADC, FIFO and SPI interface
    • Enable to use reasonable PCB, less BOM and easy assembly
    • Small package (9.0mm x 9.0mm, BGA package)
  • ●Low power consumption

    • 4-Level operation states (Shutdown, Deep Sleep, Light Sleep, Sensing)
    • Intelligent power control sequencer managing flexible duty cycle operation
    • 1mW average power consumption at 2D location sensing(*2)
    • *1:Depending on sensor configuration and environmental conditions. To be changed according to further study

      *2:In case of conditions that Socionext assumed
