DocumentDocumentShenzhen EasyDetek Technology Co.,Ltd EDC18D Manual (Model: EDC18D) 1. Product Description The EDC18D module designed based on the 5.8GHz Ultra Low Power Microwave Radar Induction Chip AT58LP1T1DB. This chip is based on the principle of Doppler effect development, using mature CMOS technology, highly integrated microwave transceiver, IF signal processing and filtering on one chip. Because the adaptive calibration algorithm is integrated on chip, the problems of in-band interference, out-of-band blocking and environmental interference are effectively solved, and the reliability and practicability of the sensor are greatly improved. The EDC18D module is powered by the TM56M1511 power manage chip, and the microwave signal generated by the PLL inside the RF-IC (AT58LP1T1DB) is amplified by PA and radiated out through the ANT-TX antenna. The microwave signal will reflect when it encounters an object in the air. When the object is in motion, there is a certain frequency difference between the reflected signal and the transmitted signal. The reflected signal received by the ANT-RX is mixed with the transmitted signal to obtain the corresponding intermediate frequency information. MCU processes and analyzes the intermediate frequency signal, while MCU also continuously detects the CDS signal. Finally, the MCU determines the CDS signal and IF signal for final OUT output control. EDC18D 2.
