Using Linear Equalizers to Shape 
HFC Network Frequency Response 
Application Note 

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: 

 

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 

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.
