1. A filter circuit, comprising:

  • a pass band filter portion disposed along a signal path between a provider-side port and a user-side port, the pass band filter portion configured to pass a first frequency spectrum in a provider bandwidth and attenuate a second frequency spectrum in a home network bandwidth; and

    a multipath interference mitigation leg operatively branched in parallel from the pass band filter portion, the multipath interference mitigation leg configured to decrease multipath distortions by improving a return loss characteristic of the home network bandwidth,wherein a frequency response of the filter circuit comprises a respective insertion loss characteristic in the provider bandwidth and in the home network bandwidth between the provider-side port and the user-side port, the insertion loss characteristic being less in the provider bandwidth than in the home network bandwidth, the frequency response further characterized by a return loss characteristic at the user-side port, andwherein the second frequency spectrum in the home network bandwidth is distinct from and higher than the first frequency spectrum in the provider bandwidth.
