Description

K-MC4 is a Doppler Transceiver with an

asymmetrical

beam

and

two

receiver

antennas. This configuration allows measuring

the angle of moving objects. This technique is

often simply called “Monopulse Radar”, but in

fact it is a

“Phase-Comparison Monopulse”

technique.

Target deviation of +/-15° from main axis

results in a phase deviation of +/- 100° at the

IF outputs I1/I2 or Q1/Q2 respectively.

The unique "RSW" Rapid Sleep Wakeup func-

tion with <5µs wakeup time makes this module

ideal for battery operated equipment. Typical

duty cycle in RWS mode may be < 1% 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.

A powerful evaluation kit ST200 is available.
