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 branched in parallel from the pass band filter portion, the multipath interference mitigation leg configured to decrease multipath distortions by improving a return loss of the home network bandwidth, wherein a frequency response of the filter circuit comprises;

    a first insertion loss in the provider bandwidth that is less than 3 dB;

    a second insertion loss in the home network bandwidth that is more than 20 dB; and
