Analysis of the distribution of gap interaction impedance coefficients of resonant coupled cavity output section of broadband klystrons

From the lumped circuit elements point of view, the distribution of gap interaction impedance coefficients of resonant coupled cavity output section of broadband klystrons is analyzed. The following topics are discussed: (1) the selection of equivalent circuit; (2) the calculation of impedance distribution with given parameters of the lumped circuit element; (3) the calculation of transfer impedance and microwave circuit parameters with measured self-impedances.
