Context: For the design of the filter model that presents the channel established by the load of a single-phase topology, the transmission lines of distributed parameters are transformed to concentrated parameters. Each line of the backbone assimilates the transmission parameter matrix and its transformation into admittance parameters, both represented within a two-port model.Method: With the single-phase topology energized at frequencies between 1,8 MHz and 30 MHz a system with BPL (Broadband Power Line) technology tensions and transfer functions of the channels are obtained. Techniques of networks synthesis are applied to the transfer functions, to obtain the filter network associated to the channel.Results: The operation of the filter in the channel of the load farthest from the source BPL, is validated by maximum transfer of power, replacing the load by the filter, to verify similar results of Signal to Noise ratio and Capacity of Channel.Conclusions: When the load is replaced by the filter, the behavior of the channel is similar, because the filter assumes the average impedance. As future work are suggested to use validated parameters of electrical conductors within the Colombian normativity to standardize the single-phase topology by distance and number of nodes, subject to the filter model associated to the longest channel to establish patterns respect to: attenuation, capacity of channel and signal to noise ratio.
