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.

OUTLINE DIMENSIONS Figure 3: Outline dimensions A P P L I C AT I O N N O T E S Sensitivity and Maximum Range The values indicated here are intended to give you a ‘feeling’ of the attainable detection range with this module. It is not possible to define an exact RCS (radar 4 cross section) value of real objects√σ because reflectivity depends on many parameters. The RCS variations however influence the maximum range only by 4√σ .

I N T E G R AT O R S I N F O R M AT I O N Installation Instruction Mechanical enclosure It is possible to hide the sensor behind a so called radome (short for radar dome) to protect it from environmental influences or to simply integrate it in the case of the end product. A radar sensor can see trough different types of plastic and glass of any colour as long as it is not metallized. This allows for a very flexible design of the housing as long as the rules below are observed. – Cover must not be metallic.

United States (FCC) and Canada (ISED) This module has been granted modular approval for fixed and/or mobile applications by FCC and ISED. Testing for the modular approval has been performed in CW mode with an open VCO input. This setup can easily be used by the customer for certification purposes. This module meets the title 47 of the Code of Federal Regulations, part 15 section 15.249 for intentional radiators operating in the 24.00 to 24.25 GHz band.

Europe (CE-RED) This module is a Radio Equipment Directive assessed radio module that is CE complaint and have been manufactured and tested with the intention of being integrated into a final product. According to the RED every final product that includes a radio module is also a radio product which falls under the scope of the RED. This means that OEM and host manufacturers are ultimately responsible for the compliance of the host and the module.
