A l I sense K-Band Doppler RF Transceivg Mroldeui
Users Manual
DF6 series of microwave motion sensor modules are
K~Band Bi-statio DRO Doppler transceiver front-end
module. These modules are designed for speed
detection with direction of motion recognition, traffic
applications and other innovative ideas.
The module consists of Dielectric Resonator IF amplifier
Oscillator (DRO), balanced mixers, and patch
antenna, built-in LNA tor high sensitivity and a pre- —
amplifier (see Figure A). EN Vin I Q

3. Powar Suppl
The minimum input voltage is 26 V and the maximum is 545 V. As there is a built-in voltage
regulation in DF6 series sensor module, fluctuation in the power supply will not affect the
performance of the module.
4. Usin ENABLE in 1)
When this pin is driven LOW (GND), this will activate the DRO and hence transmit the signal.
On the other hand, when it is driven HIGH (typically +5V), the DRO will be tie-activated, This
feature can be used to reduce power consumption by introducing pulse to this pin.
5. Radiation Pattern
The module 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 3dB beamwidth are shown in below diagram.

6. O ut Si nais
Doppler shift ~ Doppler-shift signals of ideally 90" phase difference between them appears at
I & 0 channels when movement is detected. These signals are pro-amplified by built-in lF
amplifiers for better sensitivity and better isolation. The magnitude of the Doppler Shift after
these amplifications is typically within 1V 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 095.1-1991 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 Suppor-
