BSE 2 81 Electrons se > (Sat com & Sensor Systems) Co Aid | eer DE300-0 series of microwave motion sensor modules are K-Band Bristle 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 Achievable Resonator Oscillator (DRO) balanced mixers, and patch antenna, builtin LNA for high sensitivity and a amplifier [see Fine AL Figure AL Block Diagram: AE Ln ney B-way 2.
Bim he ST Tectonics Ea us [Sate om & Sensor System! Users Manual Au GT BLL The recommended power supply is BY. The minimum input voltage and the maximum there is a built-in voltage regulation in DE300-0 sensor module, fluctuation in the power supply will not affect the performance of the module. aa Ee Vileness this pin is driven LOW (GRIND, this will activate the DRO and hence transmit the signal, On the other Band when iris driven HIGH Typically +5V), the DRO will be deactivated.
