FIELD: electrical engineering.
SUBSTANCE: proposed microwave filter has resonator incorporating below-cutoff waveguide section accommodating resonators and resonant-frequency adjusting device. Pairs of resonators and adjusting screws are alternating with pairs of adjusting screws disposed on opposite walls of below-cutoff waveguide.
EFFECT: provision for stepless adjustment of electrical connections between resonators on below-cutoff waveguides.
