Connecting Multiple Wideband Main Hubs to a Duplex Repeater
or BTS
WARNING:
Only TE personnel or TE-authorized installation person-
nel should connect the Fusion Wideband Main Hub to a base station or
repeater. Exceeding the maximum input power could cause failure of
the Fusion Wideband Main Hub (refer to Section 5.2 on page 5-4 for
maximum power specifications). 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 Wideband Main Hubs, 3x1 for three, 4x1 for four, and so.)
• 2 N-male to N-male coaxial jumper cables to connect each Fusion Wideband Main
Hub’s RF Band to the power combiner/splitters
• 1 circulator
• 1 N-male to N-male coaxial jumper cable between each circulator and the repeater
or base station
• 1 N-male to N-male coaxial jumper cable between each circulator and power com-
biner/splitter
Procedure:
1.
Connect the circulator to the repeater or base station using one N-male to N-male
coaxial jumper cable.
2.
Connect each power combiner/splitter to the circulator using one N-male to
N-male coaxial jumper cable per combiner/splitter.
3.
Connect the power combiner/splitter to the Hubs using N-male to N-male coaxial
jumper cable:
a.
From the first Hub’s
UPLINK
(Band 1, Band 2, or Band 3) port to the first
power combiner/splitter
b.
From the first Hub’s
DOWNLINK
(Band 1, Band 2, or Band 3) port to the sec-
ond power combiner/splitter
c.
From the second Hub’s
UPLINK
(Band 1, Band 2, or Band 3) port to the first
power combiner/splitter
d.
From the second Hub’s
DOWNLINK
(Band 1, Band 2, or Band 3) port 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.
