中文摘要 | 本文的目的是設計λ/4殘文摘合帶通濾波器。在應用上,λ/4 殘支耦合帶通濾波器首先運用 ABCD 矩陣模式建立,再經 Butterworth 響應的數學運算,一張以均值化阻抗表示的表格, 即可獲得以供設計。同時,兩張 Chebyshev 響應的均值化阻抗表亦可獲得。整個設計過程, 逕以步驟流程呈現,簡單明暸通於應用。由實驗與模擬的驗證,此一設計λ/4殘支耦合帶通濾波器的方法是適用的。 |
英文摘要 | The quarter-wavelength stub coupled band pass filter (QWSCBPF) is presented in this paper. In applications, the QWSCBPF is characterized in terms of an ABCD matrix. Using the mathematical expressions of the Butterworth response, we establish an available table of the normalized admittances for designing. In addition, the tables of the normalized admittances for Chebyshev responses are also stated. Moreover, we report the complete procedure with flow diagram for the easy design of the symmetrical QWSCBPF. Both simulation results and experimental measurements on the filter are presented and discussed. |
