摘要：The present invention discloses a power amplification device, including a firstamplification branch 210, a second amplification branch 220, a harmonic injection unit 230,and a first output matching unit 240. A first amplifier 211 in the first amplification branch210 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 isturned off for a signal of the first frequency that has a power value lower than anenabling threshold. The harmonic injection unit 230 injects a signal of the secondfrequency that is input from a second input terminal I2 to a signal of the first frequencythat is input from a first input terminal I1, to obtain a signal of the first frequency that hasundergone harmonic injection. A first output terminal O1 is configured to output thesignal of the first frequency that has undergone harmonic injection, and a second outputterminal O2 is configured to output a signal of the first frequency that is from the secondinput terminal 12, and the first output terminal O1 and the second output terminal O2are open for the signal of the second frequency. The power amplification device has asimple structure and relatively high efficiency.
