Overview
This application note addresses the selective replacement of cable equalizers with
linear equalizers for frequency response shaping in hybrid fiber-coax (HFC)
transmission networks.
This application note:
This application note:
Reviews the traditional roles of cable equalizers and linear equalizers in HFC
networks
Identifies factors that can affect overall network frequency response
Describes an alternative use for linear equalizers that can improve overall
network frequency response in certain applications
Provides implementation guidelines for this alternative use with 1 GHz
GainMaker® linear equalizers
Scope
The concepts presented in this document apply to HFC transmission networks in
general. Guidelines are provided for applying these concepts to 1 GHz GainMaker
system amplifiers and line extenders.
