Abstract: Provided is a transmission circuit capable of compensating a variation in output power caused due to a temperature change or an individual variability when the operation mode is switched without an increase in the size of the transmission circuit which switches the operation mode between a linear operation mode and a nonlinear operation mode, and capable of suppressing the deterioration of the quality of a transmission signal. In the transmission circuit, a gain setting section (160) sets the gain (target gain) of a variable gain amplifier (140), to a value which enables the variable gain amplifier (140) to operate linearly and corresponds to a comparison result (output error level) obtained through comparison between the target level of the variable gain amplifier (140) corresponding to the set power level of the transmission signal and the power level of an output signal of the variable gain amplifier (140) detected by a power detection section (150). The variable gain amplifier (140) amplifies an amplitude phase modulation signal or a phase modulation signal (phase path signal) in accordance with the target gain set by the gain setting section (160).

Abstract: A transmission circuit is capable of precisely compensating for an offset characteristic of an amplitude modulation section, and operating with low distortion and high efficiency over a wide output electric power range. A signal generation section outputs an amplitude signal and an angle modulation signal. An amplitude amplifying section inputs, to the amplitude modulation section, a signal corresponding to a magnitude of the amplitude signal having been inputted. The amplitude modulation section amplitude-modulates the angle modulation signal with the signal inputted from the amplitude amplifying section, and outputs a resultant signal as a modulation signal. The power measuring section measures an output power of the amplitude modulation section. An offset compensation section reads an offset compensation value from a memory in accordance with the output power of the amplitude modulation section, and adds the read offset compensation value to the amplitude signal.
