PROBLEM TO BE SOLVED: To provide a power amplifier module that reduces transmission loss for any of plurality of transmission signals to communicate and does not increase in size.SOLUTION: A matching circuit 30 is connected to an output terminal of a power amplifier 20. The matching circuit 30 is connected to a first output terminal Pout1 via a first switch 41, and is connected to a second output terminal Pout 2 via a second switch 42. When the matching circuit 30 and the first output terminal Pout1 are connected by the first switch 41 and the matching circuit 30 and the second output terminal Pout2 are disconnected by the second switch 42, the matching circuit 30 has a circuit configuration that is impedance-matched to a first high-frequency signal. When the matching circuit 30 and the second output terminal Pout2 are connected by the second switch 42 and the matching circuit 30 and the first output terminal Pout1 are disconnected by the first switch 41, the matching circuit 30 has a circuit configuration that is impedance-matched to a second high-frequency signal. |
