Abstract :
Calculation of resonant frequencies and the characteristics for the coupling coefficients of quarter-wave resonators with an impedance step are discussed. The problems of numerical calculation and synthesis of filters based on resonators with stepped heterogeneity are considered, experimental results are submitted for consideration.
