MRF24J40MB
3.3 Europe
The MRF24J40MB module has been certified for use in
European countries. The following testing has been
completed:
Test standard ETSI EN 300 328 V1.7.1 (2006-10):
• Maximum Transmit Power
• Maximum EIRP Spectral Density
• Frequency Range
• Radiated Emissions
Test standards ETSI EN 301 489-1:2008 and ETSI
EN 301 489-17:2008:
• Radiated Emissions
• Electrostatic Discharge
• Radiated RF Susceptibility
A helpful 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,
downloadable from the European Radio
Communications Office (ERO): http://www.ero.dk.
The end user is responsible for ensuring compliance
with harmonized frequencies and labeling
requirements for each country the end device is
marketed and sold.
3.3.1 MRF24J40MB SETTINGS
To meet ETSI requirements, the following settings must
be observed by the integrator:
• The MRF24J40MB transmit power setting
(RFCON3 0x203) cannot exceed -14.9 dB. This is
to meet the requirements of ETSI EN 300 328
v1.7.1 (2006-05), Maximum e.i.r.p. spectral
density limit, Section 4.3.2.2, “For wideband
modulations other then FHSS (e.g., DSSS,
OFDM, etc.), the maximum e.i.r.p. spectral
density is limited to 10 mW per MHz”. The output
power of the MRF24J40MB module, at this setting
with the PA enabled, is 9 dBm.
• Only channels 11 through 25 may be selected
(RFCON0 0x200).
