Abstract
A radio transmitter in which a power level of a modulated signal that has been amplified by an amplifier is detected, an error component is detected by comparing the detected power level with a theoretical value, an ideal value is calculated by adding the error component to the theoretical value, a reference level is generated by comparing the ideal value with the error component, and the gain of the amplifier is controlled based on a difference between the detected power level and the generated reference level.
