摘要： A transmission circuit precisely compensates for an offset characteristic of an amplitude modulation section and operates with low distortion and high efficiency over a wide output power range. A signal generation section outputs an amplitude signal and an angle-modulated signal. An amplitude amplifying section supplies, to the amplitude modulation section, a voltage corresponding to a magnitude of an inputted amplitude signal. The amplitude modulation section amplitude-modulates the angle-modulated signal by the voltage supplied from the amplitude amplifying section, thereby outputting a resultant signal as a modulation signal. A temperature measuring section measures a temperature of the amplitude modulation section. An offset compensation section calculates an offset compensation value in accordance with a change, in temperature of the amplitude modulation section, from the temperature of the amplitude modulation section in an initial state, and adds the calculated offset compensation value to the amplitude signal.
