GainStar 1 GHz Amplifier with 42/54 MHz Split
The 1 GHz GainStar Amplifier (GSA) is specifically designed for use in HFC networks.
The GSA provides excellent forward and reverse path performance combined with high-
reliability and a user-friendly layout. All new GainStar products share common plug-in
accessories and perform to 1 GHz in the forward path. The GSA provides two high-level
RF output ports or four lower-level RF output ports in a strand or pedestal mount
configuration.
The GSA utilizes GaAsFET technology optimized for superior distortion performance.
The GSA can be field-upgradable from a forward only configuration to a forward and reverse path
configuration. The GSA can also be field upgradable to a node. Standard plug-in attenuators can
be used to adjust the gain and equalization.
