The general transfer function of N transversal array is derived where the filtering function is mapped to Chebyshev polynomial in which all the coupling values are extracted. To demonstrate the feasibility of the approach two 2-stage bandpass dual mode filter prototypes based on parallel connected topology are fabricated and presented. The second filter prototype is incorporated with the source-load coupling in order to achieve a quasi-elliptic response for better selectivity. © 2001-2012 IEEE. %Z cited By 4
