K-LC4 is a 2 patch Doppler module with a nearly symmetrical wide beam for low cost short distance applications. Typical applications are movement sensors for security, lighting and building automation applications. This module may be an alternative or a complementary sensor for infrared PIR or AIR systems thanks to its outstanding performance / cost ratio.
The module is extremely small and lightweight. With an IF bandwidth from DC to 50 MHz it opens many new applications. The unique RFbeam circular polarized antenna form allows much wider acquisition fields than the traditional linear polarized patch antenna. Powerful starter kits (ST100 and ST200) with signal conditioning and visualization on the PC’s are available.
