中文摘要 |
本論文在於設計可應用於雙頻手機(1.8 GHz 與1.9 GHz)的雙通帶濾波器,雖然目前已有相關論文的發表,但是因為牽涉到的相關技術較為廣泛複雜,很難透過單一論文簡要的敘述很難成功設計出濾波器;另一方面,目前已發表的相關論文,其實際設計出來的濾波器通帶響應與理論值亦有相當的差距,沒有提到如何改善通帶響應的方式。本論文內容主要針對這兩方面來做改進,一方面提出全面且系統化的設計流程,讓讀者能夠清楚瞭解每個關鍵的設計環節;此外,亦探討通帶效能不如預期的現象,並提出改進的設計與微調方式,以達到最好的實際通帶表現。 |
英文摘要 |
This paper aims at designing adjacent dual-passband filters for cell phones with dual-band operation (1.8GHz/1.9GHz). Several related papers have been published recently. However, dispersive and complicated design techniques make it arduous to design an adjacent dual-passband filter successfully based on only one or two related papers. Techniques about improving the passband performances of the experimental filters are almost ignored in these published papers. In our paper, comprehensive and systematic design procedure has been addressed. The reader can clearly understand every key points in designing adjacent dual-passband filters by this paper. Besides, skills and fine tuning methods for improving passband performances have been proposed in this paper. |
