The paper analyzes the characteristic of a multiple-beam klystron output circuit, π-mode double gap cavity loaded by cutoff waveguide filter, with 3D simulation method. The research is focused on the influence of the size of the coupling port, coupling line and the capacitive metal rods in cutoff waveguide on the gap impedance. The result shows that, the size of the coupling port has strong influence on the external quality factor of the output cavity, while the size of the coupling line and the capacitive metal rods mainly affect the tuning frequency of cutoff waveguide filter. Since the coupling line brings about an additive inductance in cutoff waveguide filter, which makes the quality factor bigger and resonant band narrower, π-mode double gap cavities are not more advantageous to a
