Abstract
A filter circuit includes a filter that is disposed on a path connecting a common terminal and an input output terminal and uses a first frequency band as a pass band, a filter that is disposed on a path connecting the common terminal and an input output terminal and uses a second frequency band different from the first frequency band as a pass band, and a phase adjustment circuit that has an input terminal connected to the path and an output terminal connected to the path, and adjusts a phase of a signal in the first frequency band input from the path and outputs a signal having a phase different from a phase of the signal in the first frequency band to the output terminal, wherein the path and the path are paths through which a received signal passes.
