摘　　要：介绍了一种基于径向波导的X波段空间功率分配/合成系统和它的简化模型。利用HFSS软件,设计、仿真并制作了一个X波段五路径向波导功率合成器。仿真结果和测试结果一致性良好,测试结果显示在X波段近900 MHz的带宽范围内,其插入损耗小于0.75 dB,输入回波损耗优于20 dB,输出回波损耗优于12.5 dB,无源合成效率大于87.4%。该种功率分配/合成方案具有插入损耗低、合成效率高、结构紧凑、功率容量大且散热良好的特性,在功率合成领域具有广阔的应用前景。An X-band five-way spatial power divider/synthesizer system based on the radial waveguide is designed, simulated and made through the High Frequency Structure Simulator （HF- SS） with its simplified model given. The test results are in good agreement with the simulated results and indicate that the input and output echo losses are better than 20 dB and 12.5 dB respectively, the insertion loss is less than 0.75 dB, and the passive synthetic efficiency is more than 87.4% within the bandwidth of near 900 MHz at X band. The power divider/synthesizer can be widely used in the power synthesis field, featuring low insertion loss, high synthetic efficiency, compact structure, high power, and good heat dissipation.
