Qualified Antenna Types
This device has been designed to operate with a standard 2.14 dBi dipole antenna. Any
antenna of a different type or with a gain higher than 2.14 dBi is strictly prohibited for use
with this device. Using an antenna of a different type or gain more than 2.14 dBi will require
additional testing for FCC, CE and IC. The required antenna impedance is 50 Ω.

The MGM12P02 and MGM12P22 modules are in conformity with the essential requirements
and other relevant requirements of the Radio Equipment Directive(RED). Please note that
every application using the MGM12P will need to perform the radio EMC tests on the end
product according toEN 301 489-17. Separate RF testing is not required provided that the
customer follows the module manufacturer's recommendations and instructions and does
not make modifications e.g. to the provided antenna solutions or requirements. A formal DoC
is available via www.silabs.com
MGM12P32 module is inconformity with the essential requirements and other relevant
requirements of the Radio Equipment Directive(RED) at nominal 10 dBm transmit power.
The transmit power of the module is not limited and when an end product is using
MGM12P32, the end product manufacturer is responsible that the end product is in
inconformity of all relevant requirements of the RED.
