Abstract

A filter circuit includes a pass band filter portion configured to pass signals in a first frequency spectrum and attenuate or block signals in a second frequency spectrum. The first frequency spectrum and the second frequency spectrum do not overlap. The pass band filter portion is configured to cause a return loss of more than 10 decibels (dB) in the first frequency spectrum.

Claims

exact text as granted — not AI-modified

What is claimed is: 
     
         1 . A filter circuit, comprising:
 an input;   an output;   a pass band filter portion between the input and the output, wherein the pass band filter portion is configured to pass signals between the input and the output in a first frequency spectrum and attenuate or block signals between the input and the output in a second frequency spectrum; and   an interference mitigation portion configured to be connected to the pass band filter portion, wherein the interference mitigation portion comprises an attenuator circuit that is configured to increase a return loss at the output in the second frequency spectrum.
