SMSC CONFIDENTIAL
6.4 Module Weight
CX870: 20g
Note: Module weight applies to all versions of the module.
7 Connectors and Connections
7.1 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:
