Abstract:
A dielectric filter comprising:a dielectric block having a plurality of outer surfaces including a front surface and a planar mounting surface extending perpendicular to said front surface, said dielectric block including an excitation hole and a resonator hole, both of which extend from said front surface in a direction parallel to said mounting surface; an excitation hole conductor formed on an inner surface of said excitation hole; a resonator hole conductor formed on an inner surface of said resonator hole; an input/output electrode electrically coupled to said excitation hole internal conductor, said input/output electrode including a connection portion located on said front surface and extending along a straight line which forms an oblique angle with respect to said mounting surface and a contact portion located on mounting surface, said contact portion being offset from said excitation hole as viewed along the plane of said mounting surface; and an external conductor, which is insulated from said input/output electrode, formed on a plurality of said outer surfaces.
