| Zusammenfassung: | The invention discloses a novel power amplifier which comprises an input matching circuit, an output matching circuit and at least two efficiency adjusting circuits, the input end of the input matching circuit is connected with a radio frequency signal, and the output end of the input matching circuit is electrically connected with the adjusting end of the corresponding efficiency adjusting circuit; the input end of the output matching circuit is electrically connected with the output end of the corresponding efficiency adjusting circuit, the efficiency adjusting circuit is used for amplifying the radio frequency signal, and the voltage output by the adjusting end of each efficiency adjusting circuit is different, so that the working efficiency of each efficiency adjusting circuit is different for the same radio frequency signal. The voltages output by the adjusting ends of different efficiency adjusting circuits are set to be different, so that the linearity of the different efficiency adjusting circuits is |
