K-LC1a Radar Transceiver

Description

K-LC1a is a 8 patch Doppler module with an asymmetrical beam for lowcost short distance applications. Its typical applications are movement sensors in the security and automatic door 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 wide IF bandwidth 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. A powerful starterkit with signal conditioning and visualization is available from RFbeam.
