摘要


在本論文中之多頻帶通濾波器(四頻帶通濾波器:f1:1 GHz, FBW1:3%, |S21| =2.7 dB; f2:1.5 GHz, FBW2:2.1%, |S21| =2.3 dB; f3:1.93 GHz, FBW3:1.1%, |S21| = 3.9 dB; f4:2.15 GHz, FBW4:0.9%, |S21| = 4 dB)、(五頻帶通濾波器:f1:1 GHz, FBW1:3%, |S21| = 2.7 dB; f2:1.4 GHz, FBW2:2.7%, |S21| = 3.2 dB; f3:1.8 GHz, FBW3:1.9%, |S21| = 3.3 dB; f4:2 GHz, FBW4:2.2%, |S21| = 3 dB; f5:2.2 GHz, FBW5:2%, |S21| = 2.8 dB)、(六頻帶通濾波器:f1:0.8 GHz, FBW1:2.3%, |S21| = 2.9 dB; f2:1.2 GHz, FBW2:2.9%, |S21| = 2.34 dB; f3:1.4 GHz, FBW3:3.3%, |S21| = 2.59 dB; f4:1.8 GHz, FBW4:3.2%, |S21| = 2.24 dB; f5:2.2 GHz, FBW5:2%, |S21| = 2.67 dB, f6:2.5 GHz, FBW6:2%, |S21| = 2.64 dB)與四工器(f1:1.1 GHz, FBW1:2.3%, |S21| =3.1 dB; f2:1.4 GHz, FBW2:2.1%, |S21| =3.4 dB; f3:1.7 GHz, FBW3:2%, |S21| = 3.1 dB; f4:2 GHz, FBW4:2%, |S21| = 2.35 dB)使用半集總共振器(Semi-Lumped Resonator)所設計。因為分佈式耦合饋入技術所具有之低負載效應,因此不需要使用任何匹配網路用來設計多頻帶之電路。每一個通帶都是由一對共振器所控制,能夠增加設計上的自由度,而且使用分佈式耦合技術降低頻帶之間之負載效應,即可將多個通帶整合在一起。另外,由於使用source-and-load coupling的方式,它可以製造多重路徑與產生傳輸零點以提升通帶之選擇度。 最後,在本論文中以實作的方式之驗證設計電路的方法是正確的。

Semi-lumped resonators are used to design multi-band bandpass filters (Quad-band BPF:f1:1 GHz, FBW1:3%, |S21| =2.7 dB; f2:1.5 GHz, FBW2:2.1%, |S21| =2.3 dB; f3:1.93 GHz, FBW3:1.1%, |S21| = 3.9 dB; f4:2.15 GHz, FBW4:0.9%, |S21| = 4 dB), (Quint-band BPF:f1:1 GHz, FBW1:3%, |S21| = 2.7 dB; f2:1.4 GHz, FBW2:2.7%, |S21| = 3.2 dB; f3:1.8 GHz, FBW3:1.9%, |S21| = 3.3 dB; f4:2 GHz, FBW4:2.2%, |S21| = 3 dB; f5:2.2 GHz, FBW5:2%, |S21| = 2.8 dB), (Sext-band BPF:f1:0.8 GHz, FBW1:2.3%, |S21| = 2.9 dB; f2:1.2 GHz, FBW2:2.9%, |S21| = 2.34 dB; f3:1.4 GHz, FBW3:3.3%, |S21| = 2.59 dB; f4:1.8 GHz, FBW4:3.2%, |S21| = 2.24 dB; f5:2.2 GHz, FBW5:2%, |S21| = 2.67 dB, f6:2.5 GHz, FBW6:2%, |S21| = 2.64 dB) and quadruplexer (f1:1.1 GHz, FBW1:2.3%, |S21| =3.1 dB; f2:1.4 GHz, FBW2:2.1%, |S21| =3.4 dB; f3:1.7 GHz, FBW3:2%, |S21| = 3.1 dB; f4:2 GHz, FBW4:2%, |S21| = 2.35 dB) in this thesis. Because of distributed coupling technique generate low loading effect, the proposed circuits acquired multi-channels without the need of any matching network. Each passband govern by a respective pair of resonators are able to manipulate each passband to add design freedom, and mutli-band BPFs are integrated by employ distributed coupling technique to decrease channel-to-channel loading effect. On the other hand, Due to the method of utilizing source-and-load coupling, the proposed circuit can produce mutli-route and generate transmission zeros for enhanced passband selectively. Finally, to validate the design method, theory and experiment are displayed as well as compared in this thesis.
