New MDU6220

MDU6220

The Microwave Solutions MDU6220 Motion Detector Unit is an X-Band microwave transceiver that utilises the Doppler shift phenomenon to "sense" motion. The unit is supplied with a high gain/narrow beam antenna array and an integral microwave amplifier between the antenna and receiver making it suitable for long range focused detection. The unit, contained in a lightweight plastic housing, features a dielectric resonator stabilised FET oscillator, which provides stable operation over a broad temperature range in either CW or low duty cycle pulse mode, a low noise RF amplifier and a pair of orthogonal balanced mixers for enhanced sensitivity and direction sensing capability.

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 MDU6220 unit produces two low level output signals which can be amplified and processed to provide an audible or visual alarm. These signals are nominally orthogonal in phase and the direction of the detected target can be determined from the lead/lag between the two outputs. The unit employs low cost surface mount manufacturing techniques which are field proven as being rugged and reliable.
