The improved power amplifier has an output power restraint unit, and the output power restraint unit is capable of restraining output power of the improved power amplifier when the output power is exceedingly large. A method for restraining power of a power amplifier, the method comprises the steps of: determining whether power of output powers signal are exceedingly large through a power signal transformation unit, if yes, adjusting two variable resistor of an input amplifier unit for adjusting the power of the power signals, and outputting the adjusted power signals for driving a load via output terminals of the power amplifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power amplifier and method for restraining power of improved power amplifier","description":"The present invention is related to an improved power amplifier and a method for restraining power of the improved power amplifier.
