Problems solved by technology

[0004] Among them, although the power consumption of the power amplifier in the envelope tracking mode is relatively small, because the envelope tracking mode makes the power amplifier work in the saturation state with the highest efficiency, its linearity is relatively poor. After the radio frequency signal is amplified and output by the radio frequency amplifier, It is often easier to generate unwanted spurious signals near the main signal of the output signal, therefore, because the spurious signals are too large in the envelope tracking mode, the operating mode is switched to the average power tracking with small spurious signals mode, however, because the power consumption of the average power tracking mode is often relatively large, resulting in increased power consumption, that is to say, the existing radio frequency devices cannot take into account both the size of the spurious signal and the power consumption of the device

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a method and a device for controlling the working mode of a radio frequency device and an amplifier. Background technique [0002] The power amplifier (Power Amplifier, PA) is the main working device for the radio frequency signal transmission of the mobile phone, and it is also one of the main power consumption devices of the mobile phone at present. In order to save power consumption, power is generally saved by controlling the power supply voltage of the power amplifier. [0003] Two commonly used power amplifier voltage control modes are: average power tracking (Average PowerTracking, APT) mode and envelope tracking (Envelop Tracking, ET) mode, wherein the average power tracking mode is adjusted according to the average output power of the power amplifier The power supply voltage of the power amplifier, so as to achieve the purpose of power saving...
