11.1 Qualified Antennas
BGM220S modules have been tested and certified both with the on-board antenna and with an external antenna attached to the RF pin
(RF_2G4). Performance characteristics for the chip antenna are presented in Table 3.1 Antenna Efficiency and Peak Gain on page 7
and 4.16.1 Antenna Typical Characteristics. Details for the external antenna qualified are summarized in the table below.
Table 11.1. Qualified External Antennas for BGM220S
Antenna Type Maximum Gain Impedance
Connectorized Coaxial Dipole 3.2 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 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.
11.2 EU - CE
The BGM220S modules are in conformity with the essential requirements and other relevant requirements of the Radio Equipment Di-
rective (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/.
11.3 USA - FCC
This device complies with Part 15 of the FCC Rules when operating with the embedded antenna or with the antenna type(s) listed in
Table 11.1 Qualified External Antennas for BGM220S on page 44. Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause undesirable operation.
Any changes or modifications not expressly approved by Silicon Labs could void the user’s authority to operate the equipment.
