Abstract

The embodiment of the invention relates to a frequency control method and device, a radio frequency system and communication equipment, and the method comprises the steps: obtaining the transmitting power of a power amplifier when the power amplifier is in a working state, and determining a power level corresponding to the transmitting power; and controlling a voltage converter to be switched to aworking frequency corresponding to the power level, wherein the voltage converter is used for supplying power to the power amplifier at the working frequency. Through the steps, the working frequencyof the voltage converter can be effectively adjusted according to the running state of the communication system and the responded transmitting power, so the cross-modulation interference phenomenon in the communication system and the voltage converter is inhibited, the communication quality of the communication system is improved, and the communication experience of a user is improved.

Description

technical field

[0001] The embodiments of the present application relate to the technical field of communication, and in particular, to a frequency control method, device, radio frequency system, and communication equipment. Background technique

[0002] As communication devices become more powerful and consume more power, the standby time is gradually shortened. As users pay more and more attention to the standby time, fast charging has become the best way to solve the power consumption problem. Correspondingly, a higher input and output voltage is usually configured for the battery module of the communication device to realize the fast charging function. However, when the battery module supplies power to other devices in the communication equipment, it will interfere with the communication of the communication system, greatly affecting the communication quality of the communication system.
