Antenna Connector

The Wireless CPU's antenna connector allows transmission of the radio frequency (RF)
signals from the Wireless CPU to an external customer supplied antenna. The
connector is a micro-miniature coaxial MMCX through hole-mounted socket.
number of suitable MMCX type, mating plugs are available from the following
manufacturers:
•
•
•
The nominal impedance of the antenna interface is 50 ohms.

To bypass the MMCX connector, two PCB landing pads are available on
the underside of the Wireless CPU. The integrator can probe these pads
or solder a coaxial cable directly to them. Wavecom; however, cannot
guarantee absolute performance when connecting to the antenna in
this way due to the attenuation such a connection could potentially
cause. When connecting in this way, proceed with care.
