APPROVED EXTERNAL ANTENNA

TYPES

Transmitter Antenna (from Section 7.1.2 RSS-Gen,

Issue 3, December 2010):

The RN4020 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 per-

formed using the highest gain antenna of each combi-

nation 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.

Europe

The RN4020 module is an R&TTE Directive assessed

radio module that is CE marked and has been manu-

factured and tested with the intention of being inte-

grated into a final product.

The RN4020 module has been tested to R&TTE Direc-

tive 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 Compliance Test-

ing. A Notified Body Opinion has also been issued. All

test reports are available on the RN4020 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.

8.3.1

LABELING AND USER

INFORMATION REQUIREMENTS

The label on the final product which contains the

RN4020 module must follow CE marking requirements.

The “R&TTE Compliance Association Technical Guid-

ance Note 01” provides guidance on final product CE

marking.

8.3.2

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]

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/.

Note:

To maintain conformance to the testing

listed in Table 8-1, 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.
