| 摘 要： | 提出了一种新型宽带功分器，并利用该功分器设计出了超宽带的和差网络。此网络以功分器以及反相巴仑作为基本单元，将2器件通过空气桥背接得到等效的180o耦合器，4个这样的180o耦合器拓扑组合实现了超宽带的和差网络。实验结果表明，该网络性能优良，具有结构紧凑、加工方便和成本低的优点。

| Abstract: | In this paper, a novel power divider is proposed. Based on this power divider, a planar ultra-broadband microstrip sum-and-difference network is designed. This network employs the novel power divider and anti-phase balun as a building block. An equivalent 180o coupler is achieved by back-connecting the power divider and balun together. Four such couplers are connected to form the ultra-broadband sum-and-difference network. The features of this network are verified to be excellent, resulting in the advantages of being compact, easy manufacturing and low cost. |
