Abstract

The paper describes the results of calculating the coefficients of coupling between the resonators of the waveguide filter with the quasi-elliptical amplitude-frequency response making it possible to design filters of the eighth order with the pulsation level in the pass-band of 0.1, 0.2, and 0.3 dB and attenuation levels in the suppression level of 30, 40, 50, 60, and 70 dB given the maximum steep AFC.
