LB200
C-Band Microwave Motion Sensor Module
User Manual
V1.0
1. Introduction
LB200 microwave motion sensor is a C-Band Bi-Static Doppler transceiver module that
makes use of Doppler Effect Principle to detect motion. These modules are designed for
movement detection, like intruder alarms, occupancy modules and other innovative ideas.
The module consists of Coaxial Resonator Oscillator (CRO), microwave mixer and Dipole
antenna (see Diagram A).
This User Manual highlights some important points when designing-in LB200 module.
Diagram A: Block Diagram
2. Mounting
Terminal Pins can be used to connect the terminals (+5V, IF, GND) to amplifier circuits as well as mounting support. Other
mounting methods may be used.
Wave-soldering the module onto PCBA is possible but processes have to be evaluated to prevent deterioration. No-cleaning
process is recommended.
Caution must be taken to avoid applying pressure or stresses to the chassis of the module as it may cause performance
deterioration.
Terminal Pin
3. Power Supply
The module operates at +5 Vdc for Continious wave (CW) operation.
4. Radiation Pattern
The
module to be mounted with the Dipole antennas facing the desired detection
zone.
The user may adjust the orientation of the module to get the best coverage.
The radiation patterns of the antenna are shown in the diagram on the right.

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 (ÂľV). 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.
