Controller for optimizing stability of power amplifier

Abstract

The invention provides a controller for optimizing the stability of a power amplifier. The controller comprises a numerical control attenuator, an amplifier, a driving-stage power amplifier, a final-stage power amplifier, a single-chip microcomputer, a temperature detection chip, a power detection chip and a current detection chip. The output end of the numerical control attenuator is electricallyconnected with the input end of the amplifier. The output end of the amplifier is electrically connected with the input end of the driving-stage power amplifier. The output end of the push-stage power amplifier is electrically connected with the input end of the final-stage power amplifier. The output end of the final-stage power amplifier is electrically connected with the single-chip microcomputer through the choking coil and the current detection chip in sequence. The single-chip microcomputer is further electrically connected with the numerical control attenuator, the temperature detection chip and the power detection chip, and the power detection chip is connected between the driving-stage power amplifier and the final-stage power amplifier. Through the optimal design of the circuitstructure, the stability of the radio frequency power amplifier is improved, and the working efficiency of the radio frequency power amplifier is ensured.
