Radio frequency module
First Claim
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;
whereinthe 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; 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.
