Features

---

· Suitable for 3D motion sensing

    -  2 Tx and 2 x 2Rx antennas detect azimuth, elevation, speed and distance

    -  Wide bandwidth (up to 6.8GHz) and high accuracy linear linear FM FMCW radar

    -  Sensing area: up to 0.5m(*1) with <1cm(*2) resolution (in case of hand gestures)

· Highly integrated devices to simplify hardware design

    -  Integrated with antenna, radio, ADC, FIFO and SPI interfaces

    -  Rational PCB layout, less BOM and easy assembly

    -  Small package (7.0mm x 7.0mm, LGA package)

· Low power consumption

    -  4 levels of operation (shutdown, deep sleep, light sleep, induction)

    -  Intelligent power control sequencer with flexible duty cycle operation

    -  Average power consumption during gesture sensing is 2.5mW (* 3)

 

        *1：Depends on sensor configuration and environmental conditions

        *2： Change subject to further study

        *3： Test results based on Socionext assumptions
