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.

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.

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.

X-Band FSK Microwave Motion Sensor module HB180 Users Manual V1.00 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.

X-Band FSK Microwave Motion Sensor module HB180 Users Manual V1.00 8. Output Signals FSK Doppler shift – The two-channel IF terminal outputs two Doppler shift signal when movement is detected. The magnitude of two-channel Doppler Shift is proportional to the reflection of the transmitted energy and is in the range of microvolts (µV).

X-Band FSK Microwave Motion Sensor module HB180 Users Manual V1.00 Other than noises generate from internal electronic circuit, in actual applications, other noises may be picked up from surrounding, or other part of the electronic circuit. Special attention has to be given to the interference picked up from fluorescent light, as the 100/120 Hz noise is closed at the Doppler frequency generated by human movement.
