MULTIPATH MITIGATION CIRCUIT FOR HOME NETWORK
First Claim
1. A filter circuit having a frequency response, the 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 the frequency response comprises an insertion loss characteristic 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.

Abstract
A filter circuit is provided having multipath interference mitigation. The filter includes a signal path extending from an input to an output. The signal path includes a conductive path and a ground. A pass band filter is disposed along the signal path between the input and the output. The pass band filter passes a first frequency spectrum in a provider bandwidth, and attenuates a second frequency spectrum in a home network bandwidth. The filter circuit further includes a multipath interference mitigation leg operatively branched from the signal path. The multipath interference mitigation leg increases a return loss of the home network bandwidth. A frequency response of the filter circuit is characterized by an insertion loss characteristic between the input and the output being less than 3 dB in the provider bandwidth, and more than 20 dB in the home network bandwidth.
