The new Receiver Multicouplers
RFI’s latest addition to the expandable Receiver Multicoupler product range covers the entire 698-960 MHz
frequency range, offering excellent features and performance. They are used to improve the signal-to-noise
performance of a two-way radio system, are compatible with both analogue and digital technologies
and distribute received signals from a single antenna system to multiple base station receivers.
The two-way radio marketplace is a changing landscape. The
introduction of digital echnologies, shared networks and ever increasing
expectations for reliability have raised the bar in
receiver multicoupler requirements.
In response to these emerging demands, RFI is pleased to
announce the introduction of the latest member to its range of
high performance Receiver Multicoupler products.

options available) - Manual or programmable gain setting
- New Auto-Gain feature!
- “Full-band” operation 698-960 MHz (132-174 MHz and
380-520 MHz also available) - Integral status monitoring

RFI Releases New Auto-Gain Feature for Receiver Multicouplers
The new Auto-Gain feature automatically maintains the net gain of the
Receiver Multicoupler in the event of a failure in one half of the quadrature
LNA circuit, maintaining the wireless systems performance at its optimum
capability during the failure site. Gain compensation is automatically
restored back to its original value on rectification of the failed state.
The firmware feature now ships as standard in all Expandable Receiver
Multicoupler models and can be retrofitted into existing units by a simple
Flash upgrade to firmware version 1.1.
