| 摘 要： | 研究了一种X波段高功率宽带回旋行波放大器，它由改变了局部周期的矩形盘荷波导组成，并采用锥化引导磁场和盘的高度来提高增益和带宽。分析了器件的线性特性。利用全电磁（PIC）三维模拟程序EMC进行了数值模拟，结果表明：可以得到功率介于88~103kW，相对带宽介于16.63%~24.11%的不同微波输出。

| Abstract: | A tapered rectangular disk loaded gyro TWT amplifier with tapered guiding magnetic field and disk height, and partially decreasing period length is presented. The gain and the bandwidth are derived, the effect of the beam current, guide magnetic field, and input power on the output is numerically calculated. The output power is 88kW to 103kW with 16.63% to 24.11% relative bandwidth. |
