Connecting Multiple Fusion Main Hubs to an RF Source

You can use power combiner/splitters as splitters to connect multiple Fusion Main
Hubs in order to increase the total number of RAUs in a system. You can also use
power combiner/splitters to combine base station channels in order to increase the
number of RF carriers the system transports.
Connecting Multiple Fusion Main Hubs to a Simplex Repeater or
BTS
WARNING: Only ADC personnel or ADC-authorized installation per-
sonnel should connect the Fusion Main Hub to a base station or
repeater. Exceeding the maximum input power could cause failure of
the Fusion Main Hub (refer to Section 5.2 on page 5-4 for maximum power spec-
ifications). If the maximum composite power is too high, attenuation is required.
Considerations:
• 2 hybrid power combiner/splitters; one for uplink and one for downlink (2x1 for
two Fusion Main Hubs, 3x1 for three, 4x1 for four, and so on.)
• 1 N-male to N-male coaxial jumper cable between each power combiner/splitter
and the base station
• 2 N-male to N-male coaxial jumper cables between each power combiner/splitter
and each Fusion Main Hub RF Band (either Band 1 or Band 2)
Procedure:
Connect the power combiner/splitters to the repeater or base station using N-male
