複合積層フィルタ

Composite laminated filter

Abstract

PROBLEM TO BE SOLVED: To provide a composite laminated filter wherein problems such as disconnection of an inductance element and conductor loss are excluded and filter characteristic can be improved. SOLUTION: A laminated filter is constituted by bonding a laminate 1 and a resin molded member 2. A ground conductor 7b is stuck on the resin molded member 2. In the resin molded member 2, rod-shaped protrusions 2b, 2c or penetrating holes are formed perpendicularly on a bonding surface to the laminate 1. Conducting material 7a wherein the opposite side end portion of the bonding surface to the laminate is connected with the ground conductor 7b is stuck on the surfaces of the rod-shaped protrusions 2b, 2c or the inner surfaces of the penetrating holes, and inductance elements L1, L2 are constituted. The laminate 1 forms capacitors Ci, Cr and Cm in the inside by using a laminated structure and has I/O terminal electrodes 4, 5 and a ground terminal electrode 6. The capacitors Cr and the inductance elements L1, L2 are connected in parallel. COPYRIGHT: (C)2001,JPO
