description Disclosed in the present application is a push-pull power amplifier circuit. The push-pull power amplifier circuit comprises a differential amplifier circuit, a first balun, a first output matching circuit and a second output matching circuit. A secondary winding of the first balun comprises a first secondary coil segment and a second secondary coil segment; a first end of a primary winding is connected to an output end of a first power amplifier, and a second end of the primary winding is connected to an output end of a second power amplifier; a first end of the first secondary coil segment is connected to the first output matching circuit, and a second end of the first secondary coil segment is grounded; a first end of the second secondary coil segment is connected to the second output matching circuit, and a second end of the second secondary coil segment is grounded; when an operation mode of the push-pull power amplifier circuit is a first mode, the first output matching circuit outputs a first radio-fre
