These Receiver Multicouplers may be used to improve the signal-to-noise
performance of a two-way radio system. They are compatible with both
analogue and digital technologies and also provide the ability to distribute
received signals from a single antenna system to multiple base station receivers.
Introducing RFI’s New Expandable Receiver
Mult icoupler - RxMUX
Receiver Multicouplers
expandaBaBILITY & FLexIBILITY
These Receiver Multicouplers can be easily
expanded in the field, catering for output
capacities of up to 128 outputs.
They provide unparalleled performance
with the flexibility to configure and expand
as individual customer requirements
demand.
aTTenuaToR
a digital step attenuator is incorporated within the Receiver Multicoupler design to
provide the capability to easily configure the gain of the network’s receiver combiner
system. This attenuator setting can be configured by manually setting the Bcd
rotary switches located on the rear of the unit or via the usB programming interface.
The programming interface can be used to configure whether the Bcd or usB gain
value is used in the attenuator, and the ability to set this preference can allow the
unit to be configured without a pc, or alternatively, to prevent on-site tampering of
the system if desired.
The ease of changing the Receiver Multicoupler gain can also be used to
compensate for any additional losses introduced into the receiver combiner system
through the future addition of expansion Multicouplers - maintaining consistent
system performance throughout future expansion phases.
RF ouTpuTs
a multi-stage output divider is provided in the Receiver Multicoupler. eight (8)
RF outputs and one (1) expansion port are provided in the Receiver Multicoupler,
all utilising n-female connectors.
The expansion port can be used to expand the initial eight (8) RF outputs up to
sixteen (16) RF outputs, all of equal net gain, through the use of an expansion
Multicoupler. If the expansion port is not used it should be fitted with a 50 ohm
termination.
