Abstract
A novel algorithm to design hybrid waveguide-microstrip transversal microwave filters is proposed in this study. The
idea consists in isolating each resonator involved in the filter structure, to synthesise individually its frequency response, both in
resonant frequency and bandwidth. These separated optimisations lead to the dimensions of the filtering structure to meet the
requirements of a certain, specified transfer function. The novel algorithm introduces an iterative procedure in order to
synthesise the direct coupling term between source and load, which is always present in the hybrid filter structure. The whole
algorithm is illustrated by means of a design example, where a very good agreement between the ideal specified transfer
function and the final frequency response of the designed hybrid filter is obtained. A second different design example, which
has been manufactured and tested, is also included for validation.
