Abstract

The process of experimental study of a broadband output circuit of rectangular π-TM

310

mode double-gap cavity loaded by coaxial line filter is introduced.Meliorative structure and some improved measures aiming at the main technical difficulties are taken to obtain reliable experimental results.The tested data show that the rectangular π-TM

310

mode double-gap cavity couples with the output coaxial line moderately

the external quality factor is about 30

and the characteristic impedances along different beam holes remain uniform.The broadband output circuit of rectangular π-TM

310

mode double-gap cavity loa

ded by coaxial line filter has a relatively wide band

the bandwidth in X band reaches 800MHz

and the phase delay is linear with frequency.These tested data are consistent with simulation result and confirm the conclusions of theoretical researches.The results of this experimental study demonstrate that the broadband output circuit of rectangular π-TM

310

mode double-gap cavity loaded by coaxial line filter will be favorable to upgrading efficiency and bandwidth of X band high-power multi-beam klystrons

and the application to the practical development engineering is feasible.
