COMPOSITE DIELECTRIC FILTER

摘要

PROBLEM TO BE SOLVED: To miniaturize a composite dielectric filter for high frequencies to be used for communication equipment or the like. SOLUTION: First and second dielectric filters 2 and 3 are arranged at the opposite positions of a base substrate 1, and circuit forming parts 12 and 13 are arranged at the central side of the base substrate 1, and short-circuit edge sides 4a and 5a of the dielectric resonators 4 and 5 forming the dielectric filters 2 and 3 are arranged toward the outside of the base substrate 1.
