Details

The Microwave Solutions MDU2000 Motion Detector Unit is a miniature X-Band microwave transceiver that utilises the Doppler shift phenomenon to "sense" motion.
The unit, housed in a metal can, features a dielectric resonator stabilised oscillator, which provides stable operation over a broad temperature range in either CW or low duty cycle pulse mode and an integrated homodyne receiver for enhanced sensitivity and reliability.
This module family is available with either a +5v or +3v supply voltage. However, only the 5V versions can be bought on the website. If you would like to purchase the 3V versions, please contact us and we would be happy to advise your further.

Additional Information

Introduction

Operation

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.
