摘要
文章基于空间径向波导中心对称结构，进行了理论分析，提出了一种结构新颖的背靠背毫米波频段的24路空间微波功率分配／合成器设计方法，并进行了电磁场软件仿真。仿真结果显示，工作带宽在22GHz-27GHz，相对带宽大于24％，插入损耗最大1．6dB，回波损耗最小15dB，考虑到单个波导同轴转换带来的至少0．2dB损耗，则单个功率分配器或合成器的损耗最大仅0．5dB．该功率分配／合成器不仅具有宽工作带宽，低插入损耗和高输出功率等优点，而且结构紧凑，体积小，功率合成效率高，在未来宽带空间大功率合成应用领域有着很好的应用前景。
Based on the space radial waveguide central-symmetric structure a novel method of back-to-back mi- crowave 24-way combiner/divider is proposed through theory analysis and a simulation of electromagnetic field software is carried out. The simulated results show that, in the bandwidth range of 22-27 GHz, the relative band of the power combiner/divider is larger than 24% , that max insert-loss is l. 6dB and min return-loss is 15dB, that considering at least insert-loss 0.2 dB caused by single waveguide-coaxial transition max insert-loss of single spatial combiner/divider is only 0.5 dB. In addition, the power divider/combiner not only has the advantages of wider bandwidth, low insert-loss and high output power, but also has the advantages of small volume, compact structure, high power-combining efficiency, wide band and has good application prospects in field of wide band space high-power synthesis.
