Abstract
A dielectric wave guide filter comprising a block of dielectric material defining a plurality of resonators separated by an interior layer of conductive material. A first direct path for the transmission of an RF signal is defined by the plurality of resonators. An external substrate is coupled to an exterior surface of the block of dielectric material and defines a pair of RF signal input/output transmission vias filled with a conductive material and an interior RF signal transmission line extending between and interconnecting the pair or RF signal input/output transmission vias and providing an indirect cross-coupling path for the RF signal between two of the resonators separated by the interior layer of conductive material.
