本文利用二端网络理论,推出了磁控管谐振点驻波导数与 H 形输出变换器截止波长之间的关系式。还利用引入阻抗与 H 形输出变换器截止波长之间的关系式导出 H 形输出变换器截止波长计算公式。采用这公式设计磁控管 H形输出变换器就能使磁控管达到在较宽频带内谐振系统回路效率变化较小的要求。所得结果与实际比较相符合。
In this paper, using the two-terminal network theory, the relationship between the standing wave derivative of the magnetron resonance point and the cut-off wavelength of the H-shaped output converter is introduced. The formula for calculating the cut-off wavelength of H-shaped output converter is also derived by using the relationship between the input impedance and the cut-off wavelength of the H-shaped output converter. The use of this formula to design a magnetron H-shaped output converter enables the magnetron to achieve a small change in the efficiency of the resonant system loop over a wide range of frequencies. The result is in accordance with the actual comparison.
