SMA Connector
There is one female SMA connector on a single band RAU, one on the 800/900,
800/1900, and 900/1800 dual band RAUs, and two on the 1800/1800 dual band RAU.
The connector is a duplexed RF input/output port that connects to standard passive
antennas.
Figure 5-4 SMA Connector on the Single Band RAU
Each 800/900, 800/1900, and 900/1800 dual band RAU has a single female SMA
connector. The RAU uses a diplexer to combine the lower and upper band signals
from the lower and upper band Expansion Hubs for output to a single passive
antenna. Conversely, the uplink signals are separated into lower and upper band sig-
nals and sent to the Expansion Hubs.
The 1800/1800 dual band RAU has two female SMA connectors. The RAU combines
the signals from each of the 1800 MHz bands on the 1800/1800 dual band Expansion
Hub and passes the signals to both SMA connectors. On the uplink, all signals are
sent to both 1800 MHz bands on the 1800/1800 dual band Expansion Hub. When
attaching one passive antenna, terminate the unused connector with an SMA-type
50 ohm terminator (LGC Wireless part number 4100).
Diagrams of the dual band RAUs are shown in the following figure.
