A first amplifier 211 in the first amplification branch 210 supports a first frequency. A second amplifier 221 in the second amplification branch 220 supports the first frequency and a second frequency, and the second amplifier 221 is turned off for a signal of the first frequency that has a power value lower than an enabling threshold. The harmonic injection unit 230 injects a signal of the second frequency that is input from a second input terminal I2 to a signal of the first frequency that is input from a first input terminal I1, to obtain a signal of the first frequency that has undergone harmonic injection. A first output terminal O1 is configured to output the signal of the first frequency that has undergone harmonic injection, and a second output terminal O2 is configured to output a signal of the first frequency that is from the second input terminal 12, and the first output terminal O1 and the second output terminal O2 are open for the signal of the second frequency. The power amplification device has a simple structure and relatively high efficiency.
