DF100-0
K-Band Doppler RF Transceiver Module
Users Manual
6. Output Signals
Doppler shift - Doppler-shift signals of ideally 90
o
phase difference between them appears at
I & 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 I 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.
9. Handling
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.
