ABSTRACT:
A microwave band-pass filter has a casing, at least one dielectric resonator in the casing and at least one metallic adjusting screw supported by a wall of the casing and positioned adjacent the dielectric resonator with the tip end of the screw closely adjacent the resonator, so as to improve the sensitivity characteristics of the filter especially in the region higher than the resonance frequency.
