Abstract:	有鑑於吸收式帶拒濾波器在感知無線電與多頻多模收發機系統的應用潛力，本計畫擬開發多種新型吸收式帶拒濾波器設計，並發展止帶頻率與頻寬可調，以及微型化之吸收式帶拒濾波器設計。本計畫中，擬藉由於傳統反射式帶拒濾波器架構中引入有損共振器的方式，簡便地實現吸收式止帶，並能有效拓展至高階濾波器設計，達成所需的止帶選擇度。針對所開發的各種新型吸收式帶拒濾波器，並將發展對應的等效電路、設計公式，與設計流程，建立完整的合成方法。 ;In view of the potential of absorptive bandstop filter for applications in cognitive radio and multi-band multi-mode RF transceivers, the target of this project is to develop various novel absorptive bandstop filter designs. Novel absorptive bandstop filter with tunable stopband frequency and bandwidth as well as novel miniature absorptive bandstop filters will also be developed. The proposed absorptive bandstop filter design is based on introducing lossy resonator(s) to the conventional reflective bandstop filter, such that it can be easily extended to higher-order ones for better selectivity. Suitable equivalent-circuit models, design equations, and design procedures will also be established as effective design tools.
