分支线耦合器

WebThe branch line coupler is a signal coupler or divider which has four ports. The geometry of the coupler is shown in Figure1. The signal fed to port 1 is split equally into port 3 and 4 with one of the outputs exhibiting a 90 phase shift. The port 2 is an isolated port. The design specifications of the coupler are shown in Table.1. Webthe proposed branch line coupler is done by the summation of even mode and odd mode outputs. The four port S parameters are calculated by using the formulas given in … Web建模所需的 comsol ® 产品组合取决于多种因素，包括边界条件、材料属性、物理场接口及零件库，等等。 不同模块可能具有相同的特定功能，详情可以查阅技术规格表，推荐您通过免费的试用许可证来确定满足您的建模需求的正确产品组合。 如有任何疑问，欢迎咨询 comsol 销售和技术支持团队，我们 ... is scott cohen married
