60G Millimeter Wave Fall Detection Radar Module HLK-LD6002C Non-contact Intelligent Monitoring with 2T2R

Product introduction

HLK-LD6002C device has integrated 2 transmit and 2 receive channels, IQ down-conversion mixers, a RF VCO, a Fractional-N PLL, frequency tripler, built-in digital signal processing units, including FIR, FFT and other radar signal processing function blocks. The device includes an ARM® Cortex®-M3 Core based processor subsystem, which is responsible for radio chip configuration, control, calibration and data communications. The device is provided with a complete platform including reference design, software drivers, API guides and user documentations. The device also supports cascade-mode operation for applications that need higher accuracy and long range.
