Product Description
Bidirectional Trunk Amplifier

Description
TDA8030R(MB) bidirectional trunk amplifier is applied in middle-scale and large-scale HFC bidirectional distribution network. It amplifies the forward and reversed RF signal and compensates the loss of RF signal to provide enough RF level for the network. It is equipped with one RF input port and three RF output ports (including two allocated output ports, independent or branch output are optional). There are totally six -20dB test ports for forward/reversed input and output ports. It is convenient for tuning.
