11.1 Regulatory Certifications
11.1.1 Qualified Antennas
BGM220S modules have been tested and certified both with the on-board antennas and with external antennas attached to the RF pin
(RF_2G4). Performance characteristics for the integral antennas are presented in Table 3.1 Antenna Efficiency and Peak Gain
(BGM220S12A) on page 7, Table 3.2 Antenna Efficiency and Peak Gain (BGM220S22A) on page 7 and 4.16.1 Antenna Typical Char-
acteristics. Details for the external qualified reference antennas are summarized in the table below.
Table 11.1. Qualified External Antennas for BGM220S
Model Antenna Type Maximum Gain Impedance
BGM220S12A Connectorized Coaxial Dipole 3.2 dBi 50 Ω
BGM220S22A Connectorized Coaxial Dipole 2.8 dBi 50 Ω
Any external antenna of the same general type and of equal or less directional gain as listed in the above table, and having similar in-
band and out-of-band characteristics, can be used in the regulatory areas that have a full modular radio approval (USA, Canada, Korea,
Japan) as long as spot-check testing is performed to verify that no performance changes compromising compliance have been intro-
duced. In the particular FCC case, in order to comply with e-CFR Title 47, Part 15, Subpart C, Section 15.203 the module integrator
using an external antenna must ensure it has a unique connector or it is undetachable. In countries applying the ETSI standards, like
the EU countries, the radiated emissions are always tested with the end-product and the antenna type is not critical, but antennas with
higher gain may violate some of the regulatory limits.
When using instead an external antenna of a different type (such as a chip antenna, a PCB trace antenna or a patch) or having non-
similar in-band and out-of-band characteristics, but still with a gain less than or equal to the maximum gain listed in the table above, it
can be added as a permissive change to the existing grant/certificate. In most of these cases, some radiated emission testing is deman-
ded, but no modular or end-product re-certification is required.
On the other hand, all products with antennas having more gain than the maximum gain listed in the table above are very likely to re-
quire a full new end-product certification. Since the exact permissive change procedure is chosen on a case by case basis, please con-
sult your test house and/or a certification body for understanding the correct approach based on your unique design. You might also
want or need to get in touch with Silicon Labs for any authorization letter that your certification body might ask for.
11.1.2 EU - CE
The BGM220S modules have been tested against the relevant harmonized standards and are in conformity with the essential require-
ments and other relevant requirements of the Radio Equipment Directive (RED) (2014/53/EU).
Please note that every application using the BGM220S module will need to perform the radio EMC tests on the end product, according
to EN 301 489-17.
It is ultimately the responsibility of the manufacturer to ensure the compliance of the end-product as a whole. The specific product as-
sembly may have an impact to RF radiated characteristics, and manufacturers should carefully consider RF radiated testing with the
end-product assembly.
A formal Declaration of Conformity (DoC) is available at the product web page which is reachable starting from https://www.silabs.com/.
