 3.3V … 5V supply

 Less than 30mW power consumption

 High sensitivity, with integrated RF/IF amplifier

 Dual 30 patch antenna

 Buffered I/Q IF outputs

 Beam aperture 25°/12°

 Slim 6mm thickness construction

Applications

 Battery operated equipment

 Traffic supervision

 Object speed measurement systems

 Industrial sensors

Description

K-MC1_LP is a low current, doppler module

with an asymmetrical narrow beam for long

distance sensors. It is ideally suited for traffic

applicatons.

This module includes a RF low noise amplifier

and two 47dB IF pre-amplifiers for both I and Q

channels. The need for external analogue

electronics will be significantly reduced by this

feature.

K-MC1_LP needs 10 times less current than

our standard K-MC1 sensor and works from

3.3V or 5V power supplies.

An extremely slim construction with only 6mm

depth gives you maximum flexibility in your

equipment design.

Powerful starter kits with signal conditioning

and visualization are available.

Datasheet K-MC1_LP RADAR TRANSCEIVER 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 cross section) value of real objects because reflectivity depends on many parameters. The RCS variations however influence the maximum range only by 4  .

K-MC1_LP RADAR TRANSCEIVER Datasheet Integrators Information 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.

K-MC1_LP RADAR TRANSCEIVER Datasheet United States (FCC) and Canada (ISED) This module has been granted modular approval for fixed and/or mobile applications. The modular approval allows the end user to integrate the module into a finished product without obtaining subsequent and separate FCC/ISED approvals for intentional radiation, provided no changes or modifications are made to the module circuitry. Changes or modifications could void the user’s authority to operate the equipment.

K-MC1_LP RADAR TRANSCEIVER Datasheet 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.
