| 摘要 | A power amplifier circuit includes: a first differential amplifier that amplifies a first signal split from the input signal and outputs a second signal; a second differential amplifier that amplifies a third signal split from the input signal and outputs a fourth signal; a first transformer including a first input-side winding to which the second signal is input and a first output-side winding; a second transformer including a second input-side winding to which the fourth signal is input and a second output-side winding; a first phase conversion element that is connected in parallel with the first output-side winding and outputs a fifth signal; and a second phase conversion element that is connected in parallel with the second output-side winding and outputs a sixth signal. The first and second output-side windings are connected in series and output a signal obtained by adding voltages of the fifth and sixth signals together. | ||||||
