STF9834-1G series outdoor two-way amplifiers

Introduction:

STF9834-1G series outdoor two-way amplifiers

A use

STF9834-1G series outdoor two-way amplifiers can be used for extension amplifying and distribution amplifying in CATV and broadband communication systems.

Features

The main board of the amplifier is a multi-functional working platform that can meet the requirements of flexibility and diversified structure of interactive CATV system.  This working platform supports 1000MHz.

Forward amplifier is dual gaining design.  First stage uses Silicon hybrid integrated module, second stage uses power multiplying GaAs hybrid module.

The input port of forward amplifier has adjustable attenuator and adjustable equalize. There is output slope adjusting and output level adjusting between first gain stage and second gain stage, which makes the amplifier and the system to achieve the optimum working status.  All the adjusting can be easily fulfilled by stepping attenuators.

Use surge restraining circuit improves the ability of thunder stroke immunity and prevention on surge attacking.

Weather proof aluminum die-casting housing.

High efficiency switch power supply.
