RX3852-3408-31-24 Features:

Used in both analogue and digital radio systems the recevier multicoupler utilises a low-noise, high 3OIP, redundant quadrature amplifier (LNA) design to enhance base station receiver performance. Outputs are provided for up to eight (8) receivers and an optional output to feed an expansion multicoupler. Expansion configurations are detailed in our Recevier Multicoupler Application

-Low Noise Figure LNA offering excellent 3OIP performance
-Auto-gain feature automatically restoring net system gain during partial amplifier failure
-Compatible with both analogue and digital technologies
-Manual or programmable gain setting
-Intergral status monitoring and alarm outputs
-Broadband 380-520MHz (220-550MHz) operation
-Facilitates easy expansion up to 128 output ports


Note. A user-enabled “Auto-Gain” feature compensates net system gain to maintain optimum system performance during a partial LNA failure. The operating gain can be manually programmed via rotarty switches or configured via the comms port.
