RADIO FREQUENCY MODULE

摘要

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.

1. A radio frequency module comprising:
a transmission terminal to which a transmission signal is input; a transmission filter connected to the transmission terminal and including a ground terminal through which the transmission signal passes; a common terminal from which the transmission signal having passed through the transmission filter is output, and to which a reception signal is input; a reception filter which is connected to the common terminal, and through which the reception signal passes; a reception terminal from which the reception signal having passed through the reception filter is output; 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 including one end connected to the ground terminal and another end connected to a ground, the inductor circuit adjusting characteristics of the transmission filter; wherein the inductor circuit 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; anda 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.
