Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more clearly understood, the embodiments of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments in the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other unless there is a conflict.

[0028] figure 1 Schematic diagram of the working of the RF power amplifier. like figure 1 As shown, the radio frequency power amplifier is set in the radio frequency front-end device. After the radio frequency power amplifier amplifies the radio frequency signal sent by the radio frequency transceiver device, it is sent out through the antenna through the radio frequency channel, wherein the power supply of the radio frequency power amplifier is provided by the radio frequency power amplifier. It is p...
