Abstract:
1. A waveguide filter comprising: a monoblock of dielectric material including a plurality of exterior surfaces including opposed upper and lower exterior surfaces, opposed side exterior surfaces, opposed end exterior surfaces and at least one step for adjusting the bandwidth of the waveguide filter including a first exterior surface spaced from and generally parallel to the opposed upper and lower exterior surfaces of the monoblock; at least one input/output through-hole extending through the monoblock and spaced from 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 monablock in a relationship spaced from and opposite the opposed end exterior surfaces of the monoblock, the at least one slit being cut through one of the side exterior surfaces of the monoblock and both of the upper and lower exterior surfaces of the monoblock, the at least one input/output through-hole being located in the monoblock between 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.
