| & Q channels when movement is detected. These signals are pre-amplified by built-in IF amplifiers for better sensitivity and better isolation. The magnitude of the Doppler Shift after these amplifications is typically within 1mV peak to peak. Frequency of Doppler shift is proportional to velocity of motion. The magnitude of RF signal received by the Doppler-based transceiver depends on the detection distance and the Radar Cross Section (RCS) of the detected objects. The lagging/leading phase difference between | and Q signals provides information on the direction of motion (whether approaching or receding) 8. Radiation Safety Microwave radiation from the module is well below established safety standards for general public environment, like ANSI C95.1-1991 of USA and NRPB-G11 of United Kingdom. The module has been fully tested to specifications. Opening, tightening or loosening the chassis may result in performance deterioration. The module is an electrostatic sensitive device (ESD). Precautions shall be observed for handling and assembly. 10. Product Support Please contact our product support engineers in the factory for technical assistance whenever necessary.
