Abstract
A radio frequency module includes a transmission terminal, a transmission filter connected to the transmission terminal, a common terminal, a reception filter which is connected to the common terminal, a reception terminal, a branch point to which the common terminal, the transmission filter, and the reception filter are connected, a transmission path connecting the transmission terminal and the branch point, a reception path connecting the reception terminal and the branch point, a common path connecting the common terminal and the branch point, a matching circuit connected to the common path, and an inductor circuit that includes a first inductor that defines a propagation path through electromagnetic coupling to at least one of the transmission path, the common path, the matching circuit, and the reception path, and a second inductor that is positioned so as not to be electromagnetically coupled to the transmission path, the common path, the matching circuit, or the reception path.
