 技術摘要： |
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一輸入端，該第一放大器接收一第一訊號。該第二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於該導體上產生一感應電流。
The present disclosure relates, according to some embodiments, to a transformer power amplifier that allows for improved Q values and increased efficiency by reducing the capacitance coupling effect between metal layers and/or sidewalls of the same layer through carefully designed conductor structures in primary and secondary loops. A transformer power amplifier comprises a substrate, a conductor, a circular coil, a first amplifier, and a second amplifier, the conductor and the circular coil disposed on the substrate. A circular coil has a first input terminal and a second input terminal, in which the first input terminal and the second input terminal are spaced apart and opposite each other to form an opening. A first amplifier is connected to a first input terminal for receiving a first signal and a second amplifier is connected to a second input terminal for receiving a second signal, wherein the first signal and the second signal are differential signals.
