Description

K-LC2 is a 2 x 4 patch Doppler module with an

asymmetrical beam for lowcost short distance

applications. Its typical applications are move-

ment sensors in the security and presence

detection domain.

In building automation this module may be an

alternative for infrared PIR or AIR systems

thanks to its outstanding performance/cost

ratio.

The module is extremely small and lightweight.

With its IF bandwidth from DC to 50MHz it

opens many new applications. FSK is possible

thanks to the unique RFbeam oscillator design.

This allows to use this lowcost module even in

ranging applications.

Powerful starterkits (ST100 and ST200) with

signal conditioning and visualization on the

PC's are available.
