Abstract
A circuit structure for improving the harmonic suppression capability of a radio frequency power amplifier includes an output stage unit, a high-order harmonic suppression unit, and a low-order harmonic suppression unit. The output stage unit outputs a signal to be subjected to harmonic suppression; the high-order harmonic suppression unit comprises a first filter capacitor and a back hole, and is used for suppressing fifth or higher harmonics; the output stage unit and the first filter capacitor are connected to the ground in series by means of the back hole; the low-order harmonic suppression unit is connected to the output stage unit to suppress second, third and fourth harmonics. According to the design, the high-harmonic suppression capability of the radio frequency power amplifier is improved.
