Abstract:
To provide a power amplification device that can amplify an input signal having an envelope variation with high power-added efficiency in a wide frequency range, and a transmission device and a communication device using the power amplification device. A first orthogonal signal (Sd1) is generated by performing vector subtraction between first and second fundamental signals (Su1 and Su2) having the same amplitude and a phase difference δθ (0 degrees
