| Summary: | This paper presents a procedure for synthesizing microwave filters which allow for realization of filter with lossy responses that equivalent to lossless responses although at an increased insertion and return loss. Hence, this technique enables filter with finite unloaded Qu factor while maintaining the desired selectivity in the passband. In this paper, techniques of filter synthesis based upon classical predistortion, predistorted reflection-mode, reflection mode hybrid and even and odd mode predistortion type are compared. Numerical designs for Butterworth and Chebyshev characteristics are also demonstrated. The technique of filter synthesis with finite dissipative element would be useful in designing microwave filter for receiver systems such as in a satellite input multiplexer (IMUX). |
