中文摘要 | 新的方法使用平行耦合線設計微波瀘波器,串接多段平行耦合線形成帶通瀘波器其中每一段平行耦合線有相同的電長度,瀘波器轉移函數公式為Z領域。瀘波器結構使用最佳化演算法調整平行耦合線特性阻抗的偶模及奇模阻抗值使得其轉移函數可以接理想數位瀘波器。兩個帶通瀘波器驗証此一設計方法。 |
英文摘要 | A new formulation is presented to design parallel coupled line (PCL) filters at microwave frequencies. A cascade connection of multiple-section coupled lines forms a band-pass filter, wherein each section of PCL has the same electrical length. As a result, the transfer functions of filters are formulated in the Z domain. The filter structures are obtained by using optimization algorithm, in which the values of even-mode and odd-mode characteristic impedances of coupled lines are adjusted so that the transfer functions of coupled-line filters are close to those of ideal prototype filters. Two band-pass filters are realized in the form of microstrip lines and their frequency responses are measured to validate this new formulation. |
