MDU4210

The Microwave Solutions MDU4210 Motion Detector Unit is an X-Band microwave transceiver that utilises the Doppler shift phenomenon to "sense" motion. The unit is supplied with an integral high gain/narrow beam antenna array making it suitable for long range focussed detection. The unit, contained in a lightweight plastic housing, features an electronically tuneable dielectric resonator stabilised 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. The unit employs low cost surface mount manufacturing techniques which are field proven as being rugged and reliable.

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 tuneable transceiver incorporates provision for electronically tuning the unit over a frequency range of approximately 5MHz at room temperature. This enables frequency modulation to be applied to the transceiver or fsk ranging to be performed.

The following patents (and others) apply to the MDU4210 family of products: US Patents 6,064,276, 5,262,783, 5,208,567
