Abstract

The invention relates to a power amplifier control method and device, a power amplification system and a storage medium. The method is applied to the power amplification system, and the power amplification system comprises a power amplifier. The method comprises the following steps: when a starting moment arrives, outputting a first driving voltage to the power amplifier, and enabling the power amplifier to enter a working state and work under the driving of the first driving voltage; and under the condition that the control end voltage of the power amplifier reaches the power amplifier working bias voltage, outputting a second driving voltage to the power amplifier, and enabling the power amplifier to work under the driving of the second driving voltage, wherein the first driving voltage is greater than the second driving voltage, and the power amplifier working bias voltage is determined according to the second driving voltage. Even if the power amplifier works at the same temperature, the driving voltage output to the power amplifier can change along with time, so that the starting speed of the power amplifier is increased, and the problem of performance deterioration of the power amplifier is solved.

Description

technical field [0001] The present application relates to the technical field of power amplification, in particular to a power amplifier control method, device, power amplification system and storage medium. Background technique [0002] In the TDD (Time Division Duplexing, Time Division Duplexing) communication process, the uplink signal and the downlink signal are carried out in different time slots of the same frequency, and there is an idle guard time interval between the uplink time slot and the downlink time slot, so as to Avoid collision and mutual influence between uplink signal and downlink signal. That is, when the uplink time slot arrives, the uplink is turned on and the downlink is turned off. When the downlink time slot arrives, the downlink is turned on and the uplink is turned off. It can be seen that the uplink works in an on-off cycle, and the downlink works in an off-on cycle. [0003] The on-off control of the uplink and downlink is generally realized b...
