Distortion-correcting circuit, integrated circuit, and radio communication device

An integrated circuit comprising a phase-adjusting section for adjusting the phase of a purposed-wave component to be amplified in input signals;

• and a distortion-extracting section for extracting a distortion-correcting component obtained by inverting a distortion component generated when amplifying the input signals from the input signals to output the purposed-wave component output by said phase-adjusting section and the distortion-correcting component extracted by said distortion-extracting section by synthesizing the components,
• wherein the phase-adjusting section and the distortion-extracting section are designed at the same input impedance and input signals are input to the phase-adjusting section and distortion-extracting section in parallel while the input signals are not actively power-distributed.

A radio communication device comprising:

• a phase-adjusting section for adjusting the phase of a purposed-wave component to be amplified in input signals;
• a distortion-extracting section for extracting a distortion-correcting component obtained by inverting a distortion component generated when amplifying the input signals from the input signals, and a distortion-correcting section for synthesizing and outputting the purposed-wave component output by the phase-adjusting section and the distortion-correcting component extracted by the distortion-extracting section,
• wherein said phase-adjusting section and said distortion-extracting section are designed at the same input impedance and input signals are input to the phase-adjusting section and distortion-extracting section in parallel while the input signals are not actively power-distributed.
