ABSTRACT:
A coaxial resonator includes a ceramic body having outer surfaces including an end surface forming a connecting side. The ceramic body has a through hole extending longitudinally through the ceramic body defining an inner surface in the through hole. The end surface has an indentation formed therein surrounding the through hole. Metallizing is disposed on the inner surface and on all of the outer surfaces including the indentation except for the end surface. The metallized outer surfaces form an external conductor and the metallized inner surface forms an internal conductor. The ceramic body has notches extending inwardly from one of the outer surfaces in the vicinity of the indentation for galvanic separation of the internal conductor metallizing of the through hole and the indentation from the external conductor metallizing. The notches separate out a surface portion from the outer surface forming a connection for the internal conductor through the metallizing of the indentation.
