K-LC5 is an extended range dual channel Doppler Radar modu-
le with an asymmetrical beam for short range sensors. Dual IF I
and Q allow movement direction detection and high performance
signal processing. The FM input allows FSK or FMCW ranging
applications.
An extremely slim construction with only 6 mm depth gives you
maximum flexibility in your equipment design. Powerful starterkits
with signal conditioning and visualization are also available.
