Title
(EN) Radio-frequency emission circuit and circuit matching method
(ZH) 一种射频发射电路和电路匹配方法
Abstract
(EN)
The embodiment of the invention discloses a radio-frequency emission circuit and a circuit matching method. The circuit comprises a control unit and an at least one emission pathway unit. Each emission pathway unit comprises at least one preset matching pathway, and the control unit stores a corresponding relation be a preset emission power and a preset matching pathway in advance, wherein the control unit is configured to determine that the preset matching pathway corresponding to the received emission power as a first matching pathway and control the work of the first matching pathway according to the pre-stored corresponding relation of the preset emission power and the preset matching pathway.
