Sintesi di filtri a microonde mediante un modello a parametri distribuiti

A microwave filter synthesis techniques based on a distributed parameter model is presented. The frequency response of the filter is described in terms of the polynomial T21=S11/S21 whose roots are the reflection zeros of the filter. The procedure yields directly the scattering parameters of the various intercavity junctions which can be realized by any kind of discontinuity. In particular, the effect of the transitions waveguide-to-coaxial or waveguide-to-multiplexer can be taken into account in the synthesis procedure.
