Interfacing the Fusion Wideband Main Hub to an RF Source

7-52 InterReach Fusion Wideband Installation, Operation, and Reference Manual

CONFIDENTIAL D-620616-0-20 Rev D

d. From the second Hub’s DOWNLINK port (Band 1, Band 2, or Band 3) to the

second power combiner/splitter

NOTE: Connections should not cross Bands. For example, all Band 1 connections

should be made to the same hybrid power combiner/splitter connected to the repeater

BTS that matches the Band 1 frequency.

3. Check Hub LEDs.

After connecting and powering on the Hub, check all LEDs to ensure that the sys-

tem is operating properly.

Make sure the Hub is grounded. The warranty does not cover damage caused

when an ungrounded Hub is powered on.

NOTE: Use a 50 ohm terminator on any unused power combiner/splitter ports.

Figure 7-31 shows how to connect two Main Hubs to a simplex repeater or base sta-

tion. Connecting two Hubs increases the total number of supportable RAUs from 8 to

16.
