1. Introduction
This User Manual highlights some important points for
application with HB 180 module.
Figure1: Block Diagram
2. Mounting
Header pins can be used to connect the terminals (V1, V3, IF, GND) to the power supply,
FM signal generator and the amplifier circuits to serve as mounting support. Other
mounting methods may be used. Caution must be taken to avoid pressure or stress being
applied to the chassis of the module as it may cause performance deterioration.
Figure2: Outline Diagram
HB180 miniature microwave motion mensor is a X-Band
Bi-Static FM Doppler transceiver module. It has built-in
voltage tuned Dielectric Resonator Oscillator (VT-DRO)
and a pair of micro-strip patch antenna array, making them
ideal for OEM usage as FM transceiver or FSK ranging
motion detectors.

3. Connection
Connection Hole Definition:
1. GND: Ground;
2. V1: +5VDC (See section 4);
3. V2: NC (NOT CONNECTED);
4. V3: Tuning voltage :0~5VDC, Res<=1Kohm; (See section 4);
5. IF: Doppler Shift Output.
4. Pulse Operation
The Pulse operation of transmitter (V1) uses +5Vdc pulsed at up to 2kHz repetition frequency at a duty
cycle of 5% for lower power consumption.FM modulation signal V3 ueses pulse, sinewave, sawwave ,
etc , the FM moudlation signal frequency at up to 2KHz.

5. Transmit Frequency
The transmitter’s center frequency and power of the module are set by the factory. There is no user
adjustable part in this device.
The module is a low power radio device (LPRD) or intended radiator. Local radio communication
authority regulates use of such a device. Though user
license may be exempted, type approval of equipment
or other regulation compliance may be required.
6. FM Characteristics
The HB180 module’s electric tuning voltage range:
+0.5~5V, and the typical electric tuning sensitivity
(avg.) is -1MHz/V. The typical FM linearity is ±10%.
Figure4: Typical VCO characteristics
Annex 1 shows the allocated frequency in some countries.
7. Radiation Pattern
The module is to be mounted with the antenna patches facing to the desired detection zone. The user
may vary the orientation of the module to get the best coverage. The radiation patterns of the antenna
and their half power beam width (HPBW) are shown in below diagram.
