<p>PURPOSE: A dielectric waveguide filter is provided to improve withstanding power characteristics by interposing a dielectric plate with a higher dielectric constant than that of a dielectric waveguide resonator in a capacitively coupled path. CONSTITUTION: A dielectric waveguide resonator(11) includes an inductive window(L11) for input. A dielectric waveguide resonator(16) includes an inductive window(L17) for output. A dielectric waveguide resonator(13) and another dielectric waveguide resonator(14) are combined with a capacitive window(C14). A dielectric waveguide resonator(12) and another dielectric waveguide resonator(15) are combined with an inductive window(L10). A main coupling path serially combines a plurality of dielectric waveguide resonators.</p> |
