MRF24WN0MA/MB

This module is approved for installation into mobile

and/or portable host platforms and must not be co-

located or operating in conjunction with any other

antenna or transmitter except in accordance with

Industry Canada's multi-transmitter guidelines. End

users must be provided with transmitter operating con-

ditions for satisfying RF Exposure compliance.

4.2.3

APPROVED EXTERNAL ANTENNA

TYPES

Transmitter Antenna (from Section 7.1.2 RSS-Gen,

Issue 3, December 2010):

The MRF24WN0MA/MB module can only be sold or

operated with antennas with which it was approved.

Transmitter may be approved with multiple antenna

types. An antenna type comprises antennas having

similar in-band and out-of-band radiation patterns.

Testing shall be performed using the highest gain

antenna of each combination of transmitter and

antenna type for which approval is being sought, with

the transmitter output power set at the maximum level.

Any antenna of the same type having equal or lesser

gain as an antenna that had been successfully tested

with the transmitter, will also be considered approved

with the transmitter, and may be used and marketed

with the transmitter.

When a measurement at the antenna connector is

used to determine RF output power, the effective gain

of the device's antenna shall be stated, based on mea-

surement or on data from the antenna manufacturer.

For transmitters of output power greater than 10 milli-

watts, the total antenna gain shall be added to the mea-

sured RF output power to demonstrate compliance to

the specified radiated power limits.

Modular approval testing of the MRF24WN0MA/MB

module was performed with the antenna types listed in

Table 3-1.

4.3

Europe

The MRF24WN0MA/MB module is an R&TTE Directive

assessed radio module that is CE marked and has

been manufactured and tested with the intention of

being integrated into a final product.

The MRF24WN0MA/MB module has been tested to

R&TTE Directive 1999/5/EC Essential Requirements

for Health and Safety (Article (3.1(a)), Electromagnetic

Compatibility (EMC) (Article 3.1(b)), and Radio (Article

3.2) and are summarized in Table 3-1: European Com-

pliance Testing. A Notified Body Opinion has also been

issued. All test reports are available on the

MRF24WN0MA/MB product web page at http://

www.microchip.com.

The R&TTE Compliance Association provides guid-

ance on modular devices in document Technical

Guidance Note 01 available at

http://www.rtteca.com/html/download_area.htm.

4.3.1

LABELING AND USER

INFORMATION REQUIREMENTS

The label on the final product which contains the

MRF24WN0MA/MB module must follow CE marking

requirements. The “R&TTE Compliance Association

Technical Guidance Note 01” provides guidance on

final product CE marking.

4.3.2

EXTERNAL ANTENNA

REQUIREMENTS

From R&TTE Compliance Association document

Technical Guidance Note 01:

Provided the integrator installing an assessed

radio module with an integral or specific antenna

and installed in conformance with the radio mod-

ule manufacturer’s installation instructions

requires no further evaluation under Article 3.2

of the R&TTE Directive and does not require fur-

ther involvement of an R&TTE Directive Notified

Body for the final product. [Section 2.2.4]

The European Compliance Testing listed in

Table 4-1 was performed using the antenna types

listed in Table 3-1.

A document that can be used as a starting point in

understanding the use of Short Range Devices (SRD)

in Europe is the European Radio Communications

Committee (ERC) Recommendation 70-03 E, which

can be downloaded from the European Radio Commu-

nications Office (ERO) at: http://www.ero.dk/.

ment (R&TTE):

• European Conference of Postal and Telecommu-

nications Administrations (CEPT):

Note:

To maintain conformance to the testing

listed in Table 4-1, the module shall be

installed in accordance with the installa-

tion instructions in this data sheet and

shall not be modified.

When integrating a radio module into a

completed

product

the

integrator

becomes the manufacturer of the final

product and is therefore responsible for

demonstrating compliance of the final

product with the essential requirements of

the R&TTE Directive.
