am K-LC6 radar module is susceptible to electrical discharge as long as it is not pla-

ced in the circuit. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LC6 | data sheet 02 / 2020 Revision E | Page 5 / 10 O U T L I N E D I M E N S I O N S Figure 3: Outline dimensions X1 X2 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 mo-

dule. 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 ho-

wever influence the maximum range only by 4 4

. Maximum range for Doppler movement depends mainly on:

Module sensitivity S:

-126dBc ( @ 1 kHz IF Bandwidth) Carrier frequency fTX: 24.125GHz Radar cross section RCS reflectivity of the object 1): 1 m approx. for a moving person

> 50 m for a moving car note 1) RCS indications are very inaccurate and may vary by factors of 10 and more. The famous Radar Equation may be reduced for our K-band module to the following relation:

r = 0.0167 10

-s 40 4 r = 0.0167 10

-s Using this formula, you get 4 40 an indicative detection range of:

24 meters for a moving person. 62 meters for a moving car Please note, that range values also highly depend on the performance of signal processing, environment conditions (i.e. rain, fog), housing of the module and other factors. With K-LC6, you can achieve a maximum range of more than 100 m when using high resolution AD-con-

verters and selective FFT algorithms.

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. No plastic coating with colors containing metallic or Distance between cover and front of Radar sensor carbon particles. 6.2 mm Best cover material is Polycarbonat or ABS Best cover thickness is 3 4 mm Vibrations of the Radar antenna relatively to the cover should be avoided, because this generates signals that can trigger the output The cover material can act as a lens and focus or disperse the transmitted waves. Use a constant material thickness within the area used for trans-

mission to minimize the effect of the radome to the radiated antenna pattern. Detailed information about the calculati-

on and thickness for different cover mate-

rials can be found in the application note AN-03-Radome. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LC6 | data sheet 02 / 2020 Revision E | Page 7 / 10 United States (FCC) and Canada (ISED) This module has been granted modular approval for fixed and/or mobile applications. The modular appro-

val 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 users authority to operate the equipment. The end user must comply with all of the instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for complian-

ce. The finished product is required to comply with all applicable FCC/ISED equipment authorizations regulations, requirements and equipment functions not associated with the transmitter module portion. Modification to this product will void the users authority to operate this equipment. The OEM integrator is responsible for the fi-

nal compliance of the end product with this integrated modular approved transmitter module. This includes measurements with the RF module integrated and activated as defined in KDB 996369 and if applicable appropriate equipment authorizations as de-

fined in 15.101. Labelling and user information requirements RF Exposure This module is approved for installation into fixed and/

or mobile host platforms and must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC/ISED mul-

ti-transmitter guidelines. End users must be provided with transmitter operating conditions for satisfying RF Exposure compliance. If the label of the module is not visible from the outs-

ide of the end product, it must include the following texts on the label of the host product:

FCC Contains FCC ID: 2ASYV-K-LC6 ISED Contains IC: 24358-KLC6 In addition to marking the product with the appro-

priate IDs, the end product shall bear the following statement in a conspicuous location on the label or alternatively in the user manual:

This device complies with Part 15 of the FCC Rules and with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must ac-

cept any interference received, including interferen-

ce that may cause undesired operation. Le prsent appareil est conforme aux CNR dIn-

dustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes: (1) lappareil ne doit pas produire de brouillage, et (2) lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LC6 | data sheet 02 / 2020 Revision E | Page 8 / 10 An OEM integrator can show compliance to article 3.1(a) and 3.1(b) for the final product by doing internal or external tests and following the Module A (Annex II of the RED) assessment procedure. To show com-

pliance against article 3.2 it is possible to reuse the assessment of the K-LC6 as long as it is the only ra-

dio module in the final product or if the integrator can guarantee that only one radio module is operating at the same time. Test reports of the K-LC6 are available on request. The ETSI guide EG 203 367 provides de-

tailed guidance on the application of harmo-

nized standards to multi-radio and combined equipment to demonstrate conformity. RF Exposure Information (MPE) This device has been tested and meets applicable limits for Radio Frequency (RF) exposure. A detailed calculation to show compliance to the RED Article 3.1(a) is available on request. Simplified DoC Statement Hereby, RFbeam Microwave GmbH declares that the radio equipment type K-LC6 is in compliance with Directive 2014/53/EU. The declaration of conformity may be consulted at www.rfbeam.ch. 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 inclu-

des 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. The final product must be reassessed against all of the essenti-

al requirements of the RED before it can be placed on the EU market. This includes reassessing the module for compliance against the following RED articles:

Article 3.1( a ) : Health and safety Article 3.1( b ) : Electromagnetic compatibility ( EMC ) Article 3.2 :

Efficient use of radio spectrum ( RF ) The RED knows different conformity assessment procedures to show compliance against the essential requirements (See RED Guide, chapter 2.6b). As long as the radio module can show compliance to Article 3.2 by the use of a harmonized standard, which is listed in the official journal of the EU (OJEU), it is not necessary to do an EU type examination for the final radio product by a notified body. In this case it is possible to demonstrate conformity according to the essential requirements of the RED by using Module A

(Annex II of the RED), which allows to show conformi-

ty by internal production control. As long as a harmonized standard listed in the OJEU can be used to demonstrate con-

formity in accordance with Article 3.2 of the RED, it is possible to carry out the CE certi-

fication in self-declaration without the invol-

vement of a notified body. The K-LC6 shows compliance against the Article 3.2 by the use of the standard EN 300 440 which is a harmonized standard listed in the OJEU, what gives the possibility to show conformity by internal produc-

tion control. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LC6 | data sheet 02 / 2020 Revision E | Page 9 / 10 O R D E R I N F O R M AT I O N Figure 4: Ordering number structure Product
