Abstract
A dielectric ceramic filter with a metal guide can is provided. The dielectric ceramic filter includes a metal guide can coupled to and projecting from both input/output ends of the dielectric ceramic filter. Alternatively, the dielectric ceramic filter includes: a dielectric block having a plurality of vertical grooves formed in its side surfaces, wherein a conductive material is coated on all surfaces of the dielectric block except its ends; and a metal guide can covering both ends of the dielectric block, wherein the metal guide can is a conductive metal plate projecting from both ends of the dielectric block.
