Summary:In a radio frequency power amplifier with harmonic suppression, one end of an input matching circuit is connected with a radio frequency input end; and another end is connected with a base of a power amplification transistor having a collector connected with a power supply voltage through a first matching branch, and an emitter connected with a first connection point on a package substrate. The collector of the power amplification transistor is connected with a radio frequency output end through a second matching branch that is connected with the package substrate. A harmonic control circuit has a first end connected with the collector of the power amplification transistor, and a second end connected with a second connection point on the package substrate.
