摘要: | 本論文以步階阻抗低通電路為起點,提出一低通濾波器架構,利用平行共振電路原理,在原先高阻抗傳輸線上串接一段低阻抗傳輸線,並觀察濾波器參數變化對頻率響應的影響,運用電磁模擬軟體進行調整,使頻率響應內的零點與極點相互抵消,以增加濾波器截止帶的頻寬。 In this study, we propose a low-pass filter structure based on stepped-impedance low-pass filter, and a distributed parallel resonance circuit is used. The circuit has a section of high-impedance transmission line, that cascades another one with low-impedance, shunt with a coupled capacitor connecting with the terminals of two low-impedance lines. We can cancel the zero and the pole in band by using the variance of filter parameter. |
