6 EMC and ESD recommendations
The EMC tests have to be performed as soon as possible on the application to
detect any possible problem.
When designing, special attention should be paid to:
Possible spurious emission radiated by the application to the RF receiver
in the receiver band
ESD protection on SIM (if accessible from outside), serial link, etc. Refer
to paragraph 3.3.4 SIM interface.
Length of the SIM interface lines (preferably <10cm)
EMC protection on audio input/output (filters against 900 MHz
emissions), refer to paragraph 3.3.6 audio interface.
Bias of the Microphone inputs, refer to paragraph 3.3.6.2 audio
interface.
Ground plane : WAVECOM recommends to have a common ground
plane for analog / digital / RF grounds.
Metallic case or plastic casing with conductive paint are recommended
Note:
The module does not include any protection against overvoltage.
