Abstract
A system for synthesizing a microwave filter including a plurality of resonators having no tuning elements, in particular waveguide filters for use in satellite telecommunications networks. Signals representing the coupling coefficients of the coupling elements having a finite thickness and the resonant frequency of the resonators are stored in an electronic memory. A computation unit is controlled by a control unit arranged to determine automatically, in a single run, the widths of the coupling elements and the lengths of the resonators from the signals representing the coupling coefficients.
