Abstract

PURPOSE:To reduce the cost of a dielectric polar filter by providing a cover of a case accommodating the dielectric resonator with 2-stage overlap, forming a coupling hole and a rectangular waveguide by the cover as a branch and providing a coupling adjusting screw and a branch electric length adjusting screw to the cover of the branch. CONSTITUTION:An input signal A to the 1st stage dielectric resonator 1 is coupled with a branch 300 of a rectangular waveguide formed by a cover 31, 32 through a coupling hole 321 of the cover 32, synthesized to the final stage dielectric resonator 3 by the coupling hole 321 through recombination, the pole of attenuation is caused at a prescribed frequency depending on the electric length of the branch 300 and the resonator acts like a polar filter. The electric length of the branch 300 is adjusted by screws 311, 312 of the cover 31 to adjust the coupling between the 1st stage resonator 1 and the final stage resonator 3 by the screws 321A, 322A of the holes 321, 322. The center frequency f0 is matched with an optional frequency in a prescribed band by the adjusting screws to obtain a low cost dielectric polar filter.
