3. Antenna Connector
The module’s antenna connector allows transmission of the radio
frequency (RF) signals from the module to an external customer-
supplied antenna. The connector is a micro-miniature coaxial MMCX
surface mounted component. A number of suitable MMCX type,
mating plugs are available from the following manufacturers;
• Amphenol;
• Suhner;
• IMS Connector Systems.
The electrical characteristics of the antenna interface are shown below.
