Abstract
A radio-frequency module utilizing carrier aggregation includes a switch circuit that includes one input terminal and three or more output terminals and that simultaneously connects the input terminal and each of two or more output terminals selected from the output terminals, signal paths that propagate signals of corresponding frequency bands, band pass filters in the signal paths, and variable matching circuits in the signal paths. The circuit states of the variable matching circuits are changed in accordance with a combination of two or more signal paths simultaneously connected to the input terminal.
Claims10
A radio-frequency module comprising:
- a switch circuit that includes one input terminal and three or more output terminals and that allows simultaneous connection between the input terminal and each of two or more output terminals selected from the three or more output terminals;
- at least three filters that are each connected to a corresponding one of the at least three output terminals;
- and
- a variable matching circuit connected between at least one filter of the at least three filters and the switch circuit;
- wherein
- the switch circuit controls the variable matching circuit.
