Abstract: A balanced Doherty power amplifier circuit and a radio transmitter is provided. The circuit includes a first peak amplifier, where an input end of the first peak amplifier is connected to a first input end of the circuit, and a first mean amplifier, where an input end of the first mean amplifier is connected to a second input end of the circuit, and an output end of the first mean amplifier is connected to an input end of a first matching unit. The circuit also includes a second peak amplifier, where an input end of the second peak amplifier is connected to the first input end of the circuit; and a second mean amplifier, where an input end of the second mean amplifier is connected to the second input end of the circuit, and an output end of the second mean amplifier is connected to an input end of the second matching unit.
