摘要
针对高功率微波系统对馈电网络轻重量和小体积等小型化要求,提出一种工作在L波段的紧凑型同轴TEM到4路矩波导TE10的功率分配器。本文首先给出了紧凑型功率分配器的结构,并在同轴传输线中加入"十"字金属杆抑制角向高阶模反射,之后对功率分配器的几何参数进行了全局优化设计,使得在工作频点1.575 GHz时,每路输出端传输系数为-6.2 d B,各阶模式反射均低于-20 d B;通过对模式变换器内的电场幅值分布进行分析,设计功率容量可达到7 GW,且具有非常紧凑的体积,轴线长度仅约0.2 m。
A novel compact power divider, which converts TEM mode of coaxial waveguide to 4-port TE10 mode of rectangular waveguide, is provided to meet the compact requirement of the HPM system. The structure of the compact power divider is given, and a cross rod is adopted in the coaxial transmission line to suppress the high mode reflection. The geometric parameters of the divider are optimized, the S-parameter of-6 d B at the output port and reflection radio below-20 d B of each mode at the input port are obtained. The designed power capability of the power divider is as high as 7.1 GW according to the electric field analysis, and it is very compact with an axial length only about 0.2 m.
