Abstract:	為能實現微型化射頻前端電路之最佳化設計，本研究將發展「多功能化」的微波電路設計，藉由將數個電路方塊功能整合於微小化之單一電路的方式，而能突破製程極限、進一步大幅減小電路面積，以利單一晶片系統與單一系統封裝的實現。本研究擬先針對無線收發機射頻前端電路之關鍵被動組件，進行功能整合之設計，開發新式平衡至不平衡轉換濾波器，將平衡至不平衡轉換器、帶通濾波器、以及阻抗匹配電路功能整合於單一電路，如此能將所需電路面積進一步縮減。之後將開始整合射頻前端中的主、被動電路方塊，研發具有天線切換開關功能的帶通濾波器，以及具有帶通濾波器響應之低雜訊放大器等，最後結合上述元件，進行微型化射頻前端模組最佳化設計。本研究所提之電路元件「多功能化」的設計概念，不同於傳統針對各電路方塊各自獨立尋求最佳化設計之方式進行，而以系統應用角度出發，根據系統功能所需，尋求整體系統設計之最佳實施方式，故預期此一設計概念能於實現單一晶片系統與單一系統封裝時，達成更加的整體效能。。 ; In this study, in order to cooperate with the development of optimized design for miniature RF front-end, microwave circuit components with multi-function will be developed. In this way, multiple functional blocks can be integrated into one, such that one may break process fabrication limit and largely reduce the circuit area. This will be very helpful for the realization of system-on-a-chip and system-in-a-package. This research starts with the development of novel single-to-balanced filter, which integrate the functions of balun, bandpass filter, and impedance matching circuit. This will largely reduced the required circuit area of RF frond-end. Then, the integration of microwave active and passive components will be conducted; miniature mulit-functional circuit elements such as switchable bandpass filter and bandpass low-noise amplifier will be developed. Finally, these mulit-functional circuits will be integrated to form a miniature RF front-end, which will have optimal circuit performance. The design of multi-functional circuit elements in this study is different from the conventional way of miniature circuit design, which only focuses on the size-reduction of individual circuit elements. In contrast, the proposed design idea is based on the system point-of-view, and the goal is to seek for the best way to implement the system so as to achieve optimal performance. Therefore, it is expected that the proposed designs can help improve the system performance especially for system-on-a-chip and system-in-a-package applications. ; 研究期間 9808 ~ 9907
