Figure 3: Antenna connectors
The antenna connection is one of the most important aspects in the full product design
as it strongly affects the RF performance. Connecting cables between the module and the
antenna must have 50 Ω impedance. If the impedance of the module is mismatched, RF
performance will be reduced significantly.
Please be careful when extracting the antenna cables from a SOM-352 module.
Extracting the connector by pulling the cable may cause damage on the antenna plug
assembly. It is recommended to extract the cable using a proper extraction tool suggested
by the cable plug manufacturer. For I-PEX plugs please use
I-PEX 90192-001 or 90224-
001
