Scope
This module is a sensor for detecting the human movement using a radio-wave in the 24 GHz band. Table 1 List of Product Models
Main Structure Integrated antenna structure, the patch antenna is integrated on the module PCB. All of electric parts except interface connector are covered with metal cap.
Operation Overview 3.85.8 V input operation, LDO integrated. Implemented an internal MCU for RF frequency tuning of RF transceiver IC and intermittent operation. Internal MCU controls ON/OFF of input voltage of RF transceiver IC which is output from integrated
LDO, and this is for intermittent operation. There are 10 frequency channels. The module operates in CW or intermittent. The intermittent rate is selectable at 1kHz/2kHz. And RF ON time is 4us. Internal MCU supplies the tuning voltage to RF transceiver IC and the RF frequency is controlled by
tuning voltage. Monitors the output of the temperature sensor built into the RF transceiver IC, and if a temperature
change above a certain level is detected, frequency adjustment is performed using AFC (frequency calibration)

The intermittent rate is automatically determined from the sampling rate. When intermittent operation is disabled (CW operation), intermittent operation is not performed, so RF transmission/reception is always performed.
