Abstract :
The klystron output circuit of double coupled cylindrical coaxial cavity loaded with waveguide filters is designed and analyzed with two-port microwave network model theory. The output waveguide port is regarded as the first port, the drift tube gaps in cavity as the second one. By sweep frequency simulation with CST software, the change of scattering parameters square S212 with the frequency shows that the output circuit 3dB bandwidth is about 0.36GHz, relative bandwidth ΔF/F0 ≈ 3.7%.
