This paper describes the influence of both magnetization of substrate and length of coupling-line, on both the frequency characteristic of insertion loss and the frequency characteristic of differential phase shift of a multistrip device, and the magnetic interference in the multidigit stage-joint device. 本文讨论了磁化强度和耦合线长度对多带器件的插入损耗、差相移频率特性的影响,及多位级联式器件中各单元间的磁干扰问题。
