1. An amplifier circuit comprising:

  • a generating section that generates a first local signal and a second local signal which are used in frequency conversion of a first constant-envelope signal and a second constant-envelope signal having respective predetermined phases, the first local signal and the second local signal having a 180°

    phase difference therebetween;

    a frequency conversion section that performs frequency-conversion of the first constant-envelope signal and the second constant-envelope signal using the generated first local signal and second local signal;

    an amplifying section that amplifies the frequency-converted first constant-envelope signal and second constant-envelope signal; and

    a combining section that combines the amplified first constant-envelope signal and second constant-envelope signal.
