Admiral Microwaves has announced the availability of an 8 patch doppler module for short distance sensing applications. 

Fabricated in Switzerland by specialist manufacturer, RFBeam, the  K-LC1 doppler module features an asymmetrical beam and operates in the 24GHz K-band.

Measuring 25 x 25mm, the module operates over the IF bandwidth from DC to 50MHz.

As a result it is likely to find applications in movement sensors in security and automatic door applications.

The supplier also suggests the module can be used in the building automation sector, as an alternative to infrared PIR or AIR systems. Additional features include 80°x43° pattern and FM input.
