Abstract

The invention provides a power coupler, a terminal and a setting method for coupling parameters. The power coupler is provided with a control pin, a radio-frequency input pin, a radio-frequency outputpin, a reference end and a coupling output pin, wherein the control pin is used for receiving a control signal corresponding to an application scene; a radiant power path is formed between the radio-frequency input pin and the radio-frequency output pin; the radiant path is used for transmitting radiant power of an antenna; a coupling path is formed between the reference end and the coupling output pin; and the coupling path is used for setting the coupling parameters for coupling with the radiant power path according to the control signal. Through the embodiment of the invention, the problemof lowering of antenna radiant power due to the fact that the coupling parameters are mismatched with the application scene can be improved or eliminated.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a power coupler, a terminal and a method for setting coupling parameters. Background technique [0002] As users pursue the ultimate appearance of mobile terminals, models such as "full screen" and "all metal" are launched. These designs leave less and less space for antennas, and antennas must meet basic communication needs. Therefore, the radiation power of the antenna has gradually become a bottleneck in the development of mobile terminals. [0003] At present, the control of radiation power is mainly realized by power coupler. However, due to the load of the signal transmission path in actual use, there is often a certain deviation from the load added in the previous debugging, and the traditional power coupler has fixed coupling parameters, which cannot correct this deviation. Therefore, the power parameters obtained in the early stage debugging will not match the...
