Abstract

The application provides a radio frequency power amplifier power supply control method, device, terminal equipment and medium; the method comprises the following steps: obtaining a power supply voltage and power mapping relation table corresponding to a radio frequency power amplifier reference channel; obtaining a first power value emitted by the radio frequency power amplifier working with a reference radio frequency gain index in a non-reference channel; determining a first voltage compensation value corresponding to the non-reference channel according to the first power value and a reference power value; determining a power supply voltage of the non-reference channel according to a reference power supply voltage and the first voltage compensation value. The method can obtain an adjacent channel leakage ratio of the non-reference channel working with work parameters of the reference channel, and can compensate the power supply voltage of the non-reference channel, thus ensuring theadjacent channel leakage ratio of the radio frequency power amplifier working in a non-reference channel to meet the requirements, and enabling the radio frequency power amplifier to have a better power consumption.

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 ...
