本發明提供一種變壓式功率放大器,包括:一基板、一導體、一環狀線圈、一第一放大器及一第二放大器。其中該導體及該環狀線圈皆設置在該基板上。該導體包括一第一長條部,該環狀線圈鄰近於該第一長條部的一側,該環狀線圈包括一第一輸入端及一第二輸入端,該第一輸入端與該第二輸入端間隔地設置並彼此相對,以形成該環狀線圈的一缺口。該第一放大器電性連接該第二輸入端,該第二放大器接收一第二訊號,該第一訊號與該第二訊號為差動訊號對,以於該環狀線圈上形成一交變電流,該交變電流透過電磁感應該該導體上產生一感應電流。 A transformer power amplifier is disclosed. The transformer power amplifier includes a substrate, a conductor, a circular coil, a first amplifier and a second amplifier. The conductor and the circular coil are disposed on the substrate. The conductor includes a first elongated portion. The circular coil is at one side of the elongated portion. The circular coil has a first terminal and a second terminal, in which the first terminal and the second terminal are spaced apart and opposite with each other to form an opening. The first amplifier is connected to the first terminal for receiving a first signal and the second amplifier is connected to the second terminal for receiving a second signal, in which the first signal and the second signal are differential signals to form an alternative current on the circuit coil and generate an induced current on the conductor.
