提出了一种采用散射参数S21曲线来计算速调管双耦合孔输出腔外观品质因数的方法。首先借助仿真软件CST-MWS模拟计算了Toshiba研制的速调管(E3736)的具有双耦合孔输出腔的外观品质因数,发现计算结果与文献数据一致;然后对中科院电子所研制的S波段、具有双耦合孔输出腔的外观品质因数进行了计算,结果与冷测数据吻合,从而证明了该方法的有效性。
A method for calculating the appearance quality factor of the output cavity of a double coupled aperture of a klystron using a scattering parameter S21 curve is proposed. First of all, with the simulation software CST-MWS simulation Toshiba developed klystron (E3736) with a double coupling hole output cavity appearance quality factor and found that the calculation results consistent with the literature data; then the CAS S-band, with The appearance quality factor of the output cavity of the double coupling hole is calculated, and the result is in good agreement with the cold test data, which proves the effectiveness of the method.
