| Abstract: | The nonlinear characteristic of TWTA has been analyzed in this paper,some linearization techniques have been studied such as predistortion and feedforward technology,and a novel method has been proposed which uses predistortion and feedforward technology to make TWTA linear.At last,this paper shows and validates the result of the novel method of predistortion and feedforward with RF circuit simulation software ADS.The result provides important reference and practical value for the design of linearization technique used on TWTA. |
