    • A phase modulation section (101) generates a first modulated signal including phase information. An amplitude signal control section (103) generates a second modulated signal including amplitude information. A waveform shaping section (104), when an amplitude of the second modulated signal is larger than a regulated value generates a waveform-shaped modulated signal. An amplitude modulated voltage supply section (105) amplifies the waveform-shaped modulated signal based on the supply voltage from a voltage control section (106) and supplies the amplified signal to a power amplification section (102). The power amplification section (102) amplifies the first modulated signal based on the amplitude modulated voltage, and outputs the resultant signal. The waveform shaping section (104) adjusts the regulated value in accordance with a factor for changing a distorted power generated by the power amplification section (102), such that an ACP generated by the power amplification section (102) becomes a first predetermined value or smaller.

    • Provided is a transmitter circuit capable of outputting a transmission signal having high accuracy irrespective of bandwidth and operating with high efficiency. In the transmitter circuit 1, a delay detection section 18 selects two observation points at which angle change amounts of the complex envelope are larger than a predetermined angle threshold value and selects, as a singular point, an observation point at which a magnitude of the complex envelope is larger than that at one of the two observation points. Based on a positional relationship among the singular point, a preceding symbol, and a succeeding symbol, a relationship between delay times of the amplitude signal and the phase signal is detected. Based on the relationship between delay times of the amplitude signal and the phase signal, a delay setting section 19 sets a delay time in a delay adjuster 12. Based on the set delay time, the delay adjuster 12 adjusts the delay times of the amplitude signal and the phase signal.
