| 摘 要： | 探讨了TLCODE传输线模拟方法的基本原理、求解方法及步骤，推导了传输线驱动电阻负载、静态电感负载和混合型负载三种典型负载时末端界面电压的表达式，用PSPICE构造一个电路模型，以静态电感负载的计算结果为例，对所介绍的TLCODE方法及推导的公式模型予以验算。结果表明，在计算负载电压时，TLCODE与PSPICE的最大偏差仅为0.2%,在计算电流时，最大偏差仅为0.1%。

| Abstract: | The bent TM_(01)-TE_(11) mode converter is analyzed by theoretical calculation and numerical simulation, keeping the axes of the output port and that of the input in parallel. The mode converter is minimized by decreasing the inner radius of waveguide. The optimized results are shown as follows: the inner diameter of waveguide is 7.0 cm, the distance between the axes of the two ports of the mode converter is 8.03 cm, and the axial length is 15.11 cm. The overall power conversion efficiency exceeds 90% in the frequency range from 3.41 to 3.74 GHz and the efficiency reaches up to 95.6% at 3.60 GHz. |
