Abstract

The application provides a power supply control method and device of a radio frequency power amplifier, terminal equipment and medium. The method comprises the following steps: acquiring a mapping relation table corresponding to a reference channel of the radio frequency (RF) power amplifier, acquiring an adjacent frequency channel leakage ratio when the RF power amplifier works under the non-reference channel with the reference power supply voltage and the reference RF gain index and transmits the preset power; determining a first voltage compensation value corresponding to the non-referencechannel according to the adjacent frequency channel leakage ratio and the target adjacent frequency channel leakage ratio, and compensating the reference power supply voltage according to a first voltage compensation value to obtain the power supply voltage of the non-reference channel. Therefore, the power supply voltage of the non-reference channel is compensated according to the adjacent frequency channel leakage ratio of the non-reference channel working with the working parameter of the reference channel, thereby guaranteeing that the adjacent frequency channel leakage ratio satisfies therequirement and the power consumption of the RF power amplifier achieves the best when the RF power amplifier works at the non-reference channel.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method, device, terminal equipment and medium for controlling power supply of a radio frequency power amplifier. Background technique [0002] RF power amplifiers are an essential part of a wide variety of wireless transmitters. A radio frequency power amplifier generally has multiple channels, and one channel is usually selected as a reference channel. When the radio frequency power amplifier works on other non-reference channels, it uses the parameters of the reference channel, such as reference power supply voltage, reference radio frequency gain index, etc. to work. [0003] In actual use, since the radio frequency channel usually produces a frequency response, if all channels use the parameters of the reference channel, it is easy to cause the adjacent channel leakage ratio of some channels to fail to meet the requirements, or the power supply voltage ...
