Description

K-MC3 is a 108 patch doppler module with an

asymmetrical narrow beam for long distance

sensors. It is ideally suited for traffic supervi-

sion.

This module includes a RF low noise amplifier

and two IF preamplifiers for both I and Q

channels. The need for external analogue

electronics will be significantly reduced by this

feature.

For

special

signal

condition

applications, an additional buffered Mixer DC

output is provided. This greatly improves

flexibility in FSK ranging applications.

The unique "RSW" Rapid Sleep Wakeup func-

tion with <4us wakeup time makes this module

ideal for battery operated equipment. Typical

duty cycle in RWS mode may be < 5% with full

movement detection capability by sampling the

IF signals.

An extremely slim construction with only 6mm

depth gives you maximum flexibility in your

equipment design.

Powerful starterkits with signal conditioning

and visualization are also available. (see
