<p>A dielectric filter comprises several ceramic resonator blocks (30,40) in contiguous relationship. The individual resonator blocks are made of different ceramic materials having respectively different dielectric constants. Consequently, the resonator blocks may all have the same physical height, while having different resonant frequencies. Thus an optimum physical size may be selected for the resonator blocks, particularly with regard to packing density. <IMAGE></p> |
