Waveguide filters having a laminated dielectric structure for resonating at a predetermined frequency and having a series of longitudinally spaced resonators. A selected plural number of individual layers of high dielectric low temperature co-fired ceramic are laminated into a monolithic structure and then plated with a conductive material. Each of the individual layers is dimensioned and the number of layers is selected so that the unit resonates at the predetermined frequency. A waveguide filter is also described where a select plural number of contiguous layers of low temperature co-fired ceramic are laminated and plated with a conductive material. A series of vertically placed vias are positioned so as to form a perimeter of a waveguide filter. A plurality of individual layers of low temperature co-fired ceramic are laminated to the monolithic structure to form a laminated unit so that electrical components and the waveguide filter can be integrated into a single package.
