Description
The MDU (Motion Detector Unit) is an X-Band
microwave transceiver that utilizes the Doppler shift
phenomenon to "sense" motion. The unit is available
with either of two physically interchangeable forms;
A rugged cast metal housing or 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

Operation
MDU1020 Series
The basic principle of operation consists of detecting the frequency shift between a transmitted and a received
signal reflected back from a moving object within the field of view of the unit.
The unit produces a low level output signal which can be amplified and processed to provide an audible or
visual alarm signal and employs low cost surface mount manufacturing techniques which are field proven as
being rugged and reliable.
