WAVEGUIDE TRANSCEIVERS

Fixed Frequency

MDU19xx Series

Features



Low cost

Standard Waveguide output

Rugged, Reliable Construction

Low Power Consumption

High Sensitivity

Description

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

microwave transceiver that utilizes the Doppler shift

phenomenon to "sense" motion.

The unit, contained in a rugged diecast housing,

features a dielectric resonator stabilized FET oscillator,

which provides stable operation over

broad

temperature range in either CW or low duty cycle pulse

mode. The unit is available as a “transmit only” unit,

with a single mixer or with a pair of orthogonal mixers

for direction sensing applications.

Applications



Traffic Control

Automatic Door Openers

Speed Measurement

Direction of motion detection

Energy Management Systems

Sports Radar Guns

WAVEGUIDE TRANSCEIVERS

Fixed Frequency

MDU19xx Series

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 MDU1900 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 ascertained from the lead/lag between the two outputs

The MDU1910 unit produces a single low level output signal which can be amplified and processed to provide

an audible or visual alarm.

The MST1950 unit includes the transmitter only and can be used with a separate receiver as one end of a

microwave link.

All the units employ low cost surface mount manufacturing techniques which are field proven as being rugged
