5 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. A
number of suitable MMCX type, mating plugs are available from the following
manufacturers:
• Amphenol
• Suhner
• IMS Connector Systems
The nominal impedance of the antenna interface is 50 ohms.
Feature GSM850 E-GSM900 GSM1800 GSM1900
Frequency range (MHz) 824-894 880-960 1710-1880 1850-1990
Maximum power 33dBm (2W) 33dBm (2W) 30dBm (1W) 30dBm (1W)

Antenna VSWR 2.5:1 operating max
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.
