agile Sense DF6 series of microwave motion sensor modules are K-Band Bi-static 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 (DROP, balanced mixers, and pate ¥ 7 7 antenna, built-in LNA for high sensitivity and a pre— amplifier (see Figure Figure A: Block Diagram 6-way 2.
ha Series. ERG ETT The minimum input voltage is 2.6 V and the maximum 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. When this pin is driven LOW (GRIND, 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 DE-activated. This feature can be used to reduce power consumption by introducing pulse to this pin.
Doppler shift Doppler-shift signals of ideally 90° phase difference between them appears channels when movement is detected. These signals are per-amplified by built-in IF 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 mason.
