提出了一种波导三路功分器结构,该功分器采用E面T型缝隙耦合结构来实现功分比的调节。通过调节耦合缝隙以及感性膜片,使输入阻抗匹配并且实现等功率同相位的三路功分输出。为了实现功率合成,采用对称的两个三路功分器进行背靠背级联实现功率合成网络,仿真结果显示出良好的驻波效果和极低的插损。最终对加工出的实物进行测量,在32.5~36 GHz频段内实现了输出功率幅度不平衡度小于0.5 dB的良好效果。通过背靠背连接两个功分器实现了在33.3~35.3 GHz带宽内插损小于0.3 dB的功率分配/合成网络。
Proposed a waveguide three-way splitter structure, the power splitter using E-plane T-slot coupling structure to achieve the power ratio adjustment. By adjusting the coupling gap as well as the inductive diaphragm, the input impedance is matched and the three power outputs with equal power and phase are realized. In order to realize the power synthesis, a symmetrical two three-way power splitter is used to implement a back-to-back cascade to realize the power synthesis network. The simulation result shows a good standing wave effect and a very low insertion loss. In the end, the measured physical objects are measured and the good result is achieved that the output power amplitude imbalance is less than 0.5 dB in the 32.5-36 GHz frequency band. The power split / composite network with less than 0.3 dB insertion loss in the 33.3-35.3 GHz bandwidth is achieved by connecting two power splitters back to back.
