Title:
STRIP LINE FILTER
Document Type and Number:
Japanese Patent JP3018214
Kind Code:
B2
Abstract:
PURPOSE: To improve the manufacturing performance at the forming of an electrode for the strip line filter and at the mount.
CONSTITUTION: Input/output terminals 3R, 3L, 3R, 3L are arranged to an outer face of a 1st dielectric board 1a so that two of them are placed opposite to each other to the front side and the rear side of input/output conductor branches 7R, 7L symmetrically in the horizontal direction and in the forward/backward direction, a connection line 10 is arranged to its outer side face corresponding to the input/output terminals 3R, 3L, 3R, 3L and the connection lines 10 are arranged so that two of the lines are connected electrically to the input/output conductor branches 7R, 7L. An insulation part 6 is arranged to an outer side face of a 2nd dielectric board 1b symmetrically in the horizontal direction and in the forward/backward direction. Thus, the directivity of the filter is not caused, and it is not required to arrange direction of works at the forming of electrodes and assembling.
