A linear power amplification system for the distortion reduction is provided to output the steadily linearized amplified signal without the error amplifier through all operating ranges of amplifier. A linear amplifying system(100) comprises the first arbitration signal processing part(110), a splitter(120), the second amplifier(130), an extracting unit(140), a distortion error output unit(150), a correction signal output unit(160), a primary amplification section(170), and an output signal output unit(180). The first arbitration signal processing part outputs the first arbitration signal in which the size and phase of the input signal are adjusted. The splitter receives the first arbitration signal outputted from the first arbitration signal processing part and outputs into the first signal and the second signal. The second amplifier outputs the amplified second signal by receiving the second signal outputted from the splitter. The extracting unit outputs the sampled signal. The distortion error output unit outputs the obtained distortion error. The correction signal output unit outputs the correction signal which is the distortion error and the signal synthesized from the first signal. |
