Abstract

The application discloses a control circuit and method of a power amplifier, belonging to the communication field. The control circuit is used in a terminal, and the control circuit includes: a modem, a power control component, and the power amplifier; the modem is electrically connected to the power control component, and the power control component is electrically connected to the power amplifier and the power supply control component is electrically connected to the power supply of the terminal; the application obtains the data indication information indicating whether the terminal has data to send in subsequent time periods through the modem. When there is no data transmission in the segment, the modem can instruct the power control component to stop supplying power to the power amplifier, so as to prevent the power amplifier of the transmitter from continuously consuming power when the transmitter is in an idle state, thereby reducing the power consumption of the terminal.

Description

technical field [0001] The present application relates to the communication field, and in particular to a control circuit, control method and terminal of a power amplifier. Background technique [0002] With the development of the communication field, more and more data services are transmitted by the terminal based on the wireless communication standard, resulting in a significant increase in the power consumption of the terminal. Therefore, how to reduce the power consumption of the terminal during wireless data transmission has become an urgent problem for those skilled in the art. The problem. [0003] In related technologies, when a terminal performs wireless data transmission, an envelope tracking technology may be used to adjust the voltage of a power amplifier of a transmitter. Specifically, the terminal predicts the envelope signal strength for a period of time in the future according to the data to be sent by the terminal; when the envelope signal strength is rela...
