Connecting Multiple Fusion SingleStar Hubs to a Duplex
Repeater or BTS
WARNING:
Only LGC personnel or LGC-authorized installation per-
sonnel should connect the Fusion SingleStar Hub to a base station or
repeater. Exceeding the maximum input power could cause failure of
the Fusion SingleStar 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 SingleStar Hubs, 3x1 for three, 4x1 for four, and so.)
• 2 N-male to N-male coaxial jumper cables to connect each Fusion SingleStar
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 or Band 2) port to the first power com-
biner/splitter
b.
From the first Hub’s
DOWNLINK
(Band 1 or Band 2) port to the second power
combiner/splitter
c.
From the second Hub’s
UPLINK
(Band 1 or Band 2) port to the first power
combiner/splitter
d.
From the second Hub’s
DOWNLINK
(Band 1 or Band 2) 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.
