RTCA-LN Series is building type bidirectional amplifier, which can be used in traditional coaxial cable CATV distribution network and modern HFC broadband transmission network.
The amplifier is made of cast aluminum alloy, with good heat dissipation and compact size, which can be suitable for being installed in small cabinet. It can be installed horizontally or suspendedly. Two kinds of working voltage (local power supply and remote power supply (~ 35v-95v) or (~ 100v-265v) are optional.
Features
* Design of 5-1002Mhz bidirectional platform.
* Forward dual module & reverse single module design, forward and backward stage amplification adopts power multiplication amplification technology.
* The whole machine adopts modular design, and the partition frequency can be changed.
* The bidirectional filter is a fixed plug-in design, which can provide a variety of split frequencies.
* The fixed attenuator plug-in is used for equalization, reverse equalization, forward inter stage equalization and reverse equalization, with 1dB stepping.
* Aluminum alloy die casting molding is adopted with good heat dissipation.
* The input and output adopt the connection mode of terminal, which can be connected with various specifications of connectors.
* Maximum 10 Ampere over current.
