The article presents a technique of tuning of the waveguide band-pass filters, based on numerical modeling of its individual stages. As an example, the waveguide band-pass X-band filter with dual-mode cylindrical cavity resonators was synthesized. Then a filter prototype was manufactured, which was successfully tuned using the proposed technique. Comparison of results of calculation and experiment is presented.
