The ridge-loading ring plate traveling wave tube is a kind of high-power traveling wave tube with a relatively wide frequency band. In this paper, by using the method of field matching and variational principle, The small signal and large signal of traveling wave tube are discussed, and the effect of structure geometry and electronic parameters on the propagation of slow wave, small signal gain and non-linear effect of wave injection interaction are discussed.The results of this paper will be ridge loading loop Board traveling wave tube design provides the theoretical basis.
