Optimization Design of High Power Synthesis for Broadband TWT Power Amplifier
Combined with the mainstream synthesis architecture of power amplifiers, the principles affecting the syn-thesis efficiency of power amplifiers are analyzed. In view of the problem of low synthesis efficiency under high power conditions encountered in the development of broadband TWT power amplifiers, a phase optimization synthesis tech-nology based on power detection is proposed .The last stage synthesis efficiency of high power broadband TWT am-plifiers has been improved from 74％to 91.6％within the rated output power range.
