The invention discloses a power amplification circuit, an output end of the power amplification tube is connected with at least three forked circuits. The first forked circuit comprises a first electrical inductance, one end of which is connected with the output end of the power amplification tube and the other end used for being connected with the power source; the second forked circuit comprisesa first frequency selective network, a first capacitor and a second frequency selective network; wherein, one end of the first frequency selective network is connected with the output end of the power amplification tube, and the other end of the first frequency selective network is connected with one end of the first capacitor to form a series circuit; the other end of the first capacitor is connected with the ground and the second frequency selective network is in parallel connection with the series circuit; the third forked circuit comprises a third frequency selective network, one end of which is connected with the output end of the power amplification tube and the other end used for being connected with a load. Correspondingly, the invention also discloses a radio frequency transmitter and a base station device. By adopting the power amplification circuit of the invention, the collector peak voltage of the traditional E type power amplifier during working is reduced and the property of the power amplifier is enhanced.
