Abstract
A filter circuit includes a pass band filter and a multipath interference mitigation leg. The pass band filter is disposed along a signal path between a provider-side port and a user-side port. The pass band filter is configured to pass a provider bandwidth signal received at the provider-side port and block at least a portion of a home network bandwidth signal received at the user-side port. A frequency spectrum of the home network bandwidth signal is distinct from, and higher than, a frequency spectrum of the provider bandwidth signal. The multipath interference mitigation leg is operatively branched to ground from the signal path. The multipath interference mitigation leg is configured to increase a return loss in the home network bandwidth signal.
