Generalized Lossy Microwave Filter Coupling Matrix Synthesis and Design Using Mixed Technologies

  title={Generalized Lossy Microwave Filter Coupling Matrix Synthesis and Design Using Mixed Technologies},

This paper presents a generalized direct synthesis technique for lossy reciprocal and nonsymmetrical microwave filters. The procedure handles multiple complex coupling among resonators and finite-Q resonators. A coupling matrix model with complex entries is used as the basis for the analysis. New mathematical definitions are introduced to find the necessary properties of the complex coupling matrix. Synthesis verification examples include symmetrical, asymmetrical and different loss level lossy… CONTINUE READING
