Abstract

The configuration of aperture coupling of coaxial output cavity with shift-tubes to output rectangular waveguide of klystron is designed. The smith-chart, one-port complex reflecting coefficient and loaded quality factor of transverse magnetic higher mode TM₃₁₀ in cavity resonator coupling to transverse electric fundamental mode TE₁₀ in waveguide is investigated based on theory of one-port network theory and simulated with high frequency electromagnetic simulator. The impact of rectangular coupling aperture sizes on loaded quality factor is displayed.
