5. Output Signals
Doppler shift - Doppler shift output from IF terminal when movement is detected. The magnitude of the Doppler Shift is
proportional to reflection of transmitted energy and is in the range of microvolts (µV). A high gain low frequency amplifier
is usually connected to the IF terminal in order to amplify the Doppler shift to a processable level. Frequency of Doppler
shift is proportional to velocity of motion. Typical human walking generates Doppler shift below 100 Hz.
6. Reference Amplifier Circuit Design (CW operation)
7. 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.
8. Handling
The module has been fully tested to specifications. Upon opening, tighten or loosen the chassis will cause performance
deterioration.
The module is an electrostatic sensitive device (ESD). Precautions shall be observed for handling and assembly.
9. Product Support
Please contact our product support engineers in the factory for technical assistance whenever necessary.
