Description

The MDU (Motion Detector Unit) is an X-Band

microwave transceiver that utilizes the Doppler shift

phenomenon to "sense" motion. The unit consists of a

circuit board with a lightweight plastic housing.

The circuit features a dielectric resonator stabilized

FET oscillator, which provides stable operation over a

broad temperature range in either CW or low duty

cycle pulse mode and a balanced mixer for enhanced

sensitivity and reliability.

Applications

 Intrusion Alarms (Room, Vehicle)

 Automatic Door Openers

 Speed Measurement

 Collision Avoidance

 Traffic Control

 Presence Sensing
