PL8130A CATV RF Line Extender is an amplifier used in cable television systems. Its primary role is to compensate for signal loss caused by cables, hence increasing the distance of signal transmission on branch lines. This type of line extender amplifier is typically built in the circuit beside the trunk amplifier to ensure that the signal can cover a larger region, reduce signal loss, and increase the transmission distance of network signals.
PL8130A CATV RF amplifier is a small type of Line Extender that is applied for HFC network.
