RF Interface
The GL7x00 supports two RF connectors for a primary and a diversity antenna. These antenna
connectors allow the transmission of radio frequency (RF) signals from the device to an external
customer supplied antenna. The connector is an SMA coaxial connector (female).
The nominal impedance of the antenna interface is 50
Ω
.
Note:
The diversity antenna connector cannot be used without using the main antenna connector.
