A dielectric waveguide filter which, in one embodiment, is comprised of a plurality of monoblocks coupled together in a side-by-side relationship. In one embodiment, the waveguide filter includes two end monoblocks and two interior monoblocks each defining two resonators. First and second RF signal input/output electrodes are defined on the two end monoblocks. In one embodiment, a direct RF signal transmission path is defined in part by the combination of the resonators, RF signal transmission bridges on each of the monoblocks that interconnect the resonators on each of the monoblocks, and RF signal transmission windows between and interconnecting the resonators of adjacent monoblocks. In one embodiment, alternate or cross-coupling RF signal transmission paths are defined by external RF signal transmission lines that extend between adjacent monoblocks.
