PROBLEM TO BE SOLVED: To provide a modulation circuit capable of obtaining a high output by easily improving the distortion characteristic of a modulator. SOLUTION: A distortion correction component obtained by inverting a distortion component generated by the modulator 45 is outputted at a comparator 44 and this distortion correction component is added to a base band signal by an adder 42 to input the base band signal to the modulator 45. Thus, the distortion component is cancelled by the output of the modulator 45. |
