Abstract:
1. A waveguide filter comprising: a monoblock of dielectric material including a plurality of exterior surfaces including opposed upper and lower exterior surfaces and opposed end exterior surfaces and at least one step for adjusting the bandwidth of the waveguide filter including a first exterior surface extending from one of the opposed end exterior surfaces of the monoblock and spaced from one of the opposed upper and lower exterior surfaces of the monoblock; no more than two through-holes in the monoblock including at least one input/output through-hole extending through the monoblock and spaced from the one of the opposed end exterior surfaces of the monoblock, the at least one input/output through-hole defining first and second openings in one of the upper and lower exterior surfaces of the monoblock and the first exterior surface of the at least one step respectively; and at least one slit defined and located in the monoblock in a relationship spaced from and opposite the one of the opposed end exterior surfaces of the monoblock, the at least one input/output through-hole being located in the monoblock between the one of the opposed end exterior surfaces of the monoblock and the at least one slit, and the at least one step terminating in a second exterior surface spaced from the at least one slit.
