Abstract
A power amplifier includes a first amplifier configured to amplify a first high-frequency signal, a second amplifier configured to amplify a second high-frequency signal delayed with respect to the first high-frequency signal by at least 90 degrees, a hybrid coupler including a first transmission line and a second transmission line, a first power-supply circuit for the first amplifier, a second power-supply circuit for the second amplifier, and an output matching network. The hybrid coupler is connected to an output end of the first amplifier at a first end of the first transmission line. The first transmission line is connected to the first power-supply circuit and the output matching network at a second end. The second transmission line is connected to an output end of the second amplifier at a first end. The second transmission line is connected to the second power-supply circuit at a second end.
