VHF Expandable Receiver Multicoupler
132-174 MHz
Receiver Multicoupler
This high performance Receiver Multicoupler (Rx Mux) model is Receiver
Multicoupler a broadband, expandable unit that has been designed to cater for
analogue and digital VHF system applications.
The unit utilises a low-noise, high 3OIP, quadrature amplifier (LNA) to enhance
base station receiver performance, with inherent redundancy provided in the
quadrature design.
The Rx Mux provides outputs for up to eight (8) receivers.
The individual receiver outputs of the Rx Mux can also be used in easily field
-expandable configurations to connect up to sixteen (16) Expansion shelf units,
providing up to a maximum of 128 receiver outputs if required.
Each amplifier in the quadrature LNA, along with the internal power supplies, is
monitored to provide alarms via relay contacts and the comms port.
The unit’s operating gain can be manually programmed via rotary switches, or
configured via the comms port.
