Abstract A new kind of 3-stage filter type of output circuit for lower RF band and middle power broadband klystron, π-mode double-gap cavity loaded by Coaxial-Rectangular Waveguide output circuit, is put forward and the feasibility is demonstrated. The performance of this kind of output circuit is simulated and the influence of all parts of the output circuit on the gap impedance of the output cavity is investigated in detail. The research results show that, the coaxial-rectangular waveguide output circuit not only overcomes the obstacle of big rectangular waveguide’s impairment of focus system of beams and is of benefit to raising the efficiency, but also has a very wide band and high power capacity.
