摘要

摘要: 该文提出了一种适合于低频段中等功率的宽带速调管的新型3-节滤波器型输出电路-模双间隙腔加载同轴-矩形波导输出电路，并对输出电路的性能以及各部分结构对输出腔间隙阻抗的影响规律进行详细研究。研究结果表明，同轴-矩形波导混合型输出电路不仅克服了低频段宽带速调管中输出波导尺寸太大而影响聚焦系统的困难，有利于提高电子注通过率和整管效率，同时还具有很好的输出带宽潜力和良好的高功率承受能力。

Abstract: A new kind of 3-stage filter type of output circuit for lower RF band and middle power broadband klystron, -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 waveguides 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.
