摘要:
摘要： By analyzing various output port layouts and transmission zeros resulting from high-order resonators, the appropriate order of the packaged circuit can be determined. The optimal packaged triplexer can reduce losses and improve isolation. Compared with tapped-line structures or coupled feeding lines, design processes can be simplified by employing distributed coupling techniques in the input and output ports. With the distributed coupling techniques used, all one needs to do is modify the mismatch between every single channel and the metal package. Matching conditions of different frequency bands are no longer designed individually at the CP. Hence, the whole design procedure can be simplified dramatically. In this way, high independence and tiny impact between the adjacent channels shorten the time spent on fine tuning and debug so that these two pieces of hard ware can meet specifications and requirements in a limited time. 其他題名： MMM 出版者： New York: IEEE 出版日期： 2012-01 出處： IEEE microwave magazine, 2012-01, Vol.13 (1), p.139-145 資源來源： IEEE Electronic Library (IEL) 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
