Summary: | The present invention discloses a balanced Doherty power amplifier circuit and a radio transmitter, and relates to the field of wireless communication technologies, increasing efficiency of a power amplifier circuit. The balanced Doherty power amplifier 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; 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 by using a one-fourth wavelength line; 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 by using a one-fourth wavelength line. |
