[0004] However, the above loadpull parameter adjustment is only for the motherboard of the RF circuit. The power consumption of the whole machine after the antenna is installed is not considered during the debugging process. Therefore, after the antenna is installed, the power consumption of the electronic device during operation will be higher than the optimal power consumption point. , and battery life is reduced

Embodiment Construction
[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0032] The "plurality" mentioned herein means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.
[0033] In the related technology, since the power consumption generated by the power amplifier in the working state is the main part of the power consumption of the electronic equipment, the technicians separately debug the radio frequency circuit during the debugging phase of the electronic equipment, and comprehensively consider the various...

The embodiment of the invention discloses a control method and device of a radio frequency circuit and electronic device, and belongs to the technical field of radio frequency. The method comprises the following steps: acquiring output current of a power amplifier in a radio frequency circuit; adjusting the impedance adjustable component in response to the fact that the current value of the outputcurrent is greater than a first current threshold; obtaining the output current of the power amplifier after the ith impedance adjustment; and in response to the fact that the current value of the output current meets the adjustment ending condition, stopping adjusting the impedance adjustable assembly. According to the embodiment of the invention, the output current of the power amplifier in theradio frequency circuit is monitored, and the impedance adjustable assembly is controlled to perform adjustment when the current value is greater than the first current threshold, so that the load traction of the power amplifier is adjusted, and the working current of the radio frequency circuit is reduced to meet the adjustment end condition; therefore, the power supply current value transmittedto the radio frequency circuit by the battery of the electronic device is reduced, the radio frequency power consumption of the electronic device is reduced, and the endurance and the service life ofthe battery are improved.
Description
technical field [0001] The embodiments of the present application relate to the field of radio frequency technologies, and in particular to a control method, device and electronic equipment for a radio frequency circuit. Background technique [0002] The power amplifier (Power Amplifier, PA) in electronic equipment is an important part of the radio frequency circuit, which is used to amplify the power of the pre-stage signal to meet the signal transmission power requirement. The power consumption generated by the power amplifier in the working state is the main part of the operating power consumption of the electronic equipment, so reducing the power consumption of the power amplifier can effectively reduce the overall power consumption of the electronic equipment. [0003] In the related art, technicians debug the radio frequency circuit separately during the debugging stage of the electronic equipment, comprehensively consider each working frequency band of the power ampli...
