8 Connectors and Connections

8.1 WLAN UFL Antenna Connector (optional)

The module includes two PCB strip antennas operated in diversity mode. Alternatively, one or two coaxial antenna

connectors are provided for connecting external (to the module) antennas. The choice between using the strip antenna or

using the coaxial sockets is a build option, determined by the position of surface mount capacitors on the module PCB. If the

PCB antennas are chosen, then diversity mode is always used. If external (to the module) antenna sockets are used, then

two external antennas should be used to provide 2X diversity operation.

If external antenna is used, please choose the proper part number indicating two external antenna sockets. Do not use a

module which has two external antenna sockets with only one external antenna connected; this will result in reduced WiFi

performance.

Please see ordering guide for build option details.

The surface-mount antenna socket used in the CX module is:

UF.L type Ultra Small Surface Mount Coaxial Connector
