PROBLEM TO BE SOLVED: To reduce a circuit scale of a radio transmitter.SOLUTION: A radio transmitter 10 includes a PA15, an LUT12c, and a control part 21. The PA15 amplifies power of a radio transmission signal. The LUT12c stores a plurality of distortion compensation coefficients used for non-linear distortion compensation of the PA15. The control part 21 alternately performs reading of a distortion compensation coefficient at renewal and writing a distortion compensation coefficient, which has been adjusted based on a feedback signal, at renewal, at the time of any distortion compensation coefficient renewal within a plurality of distortion compensation coefficients stored in the LUT12c, by using any one port of the LUT12c. |
