Title:
HIGH-FREQUENCY COMPOSITE COMPONENT
Document Type and Number:
Japanese Patent JP3255105
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the parts having high performance, which can correspond to the high-frequency signals of a plurality of frequency bands that are comparatively close by connecting a two terminal switch, an LC filter and a notch filter, which are integrated into a stacked body where a plurality of dielectric layers are stacked between a first terminal arranged on an antenna-side and a second terminal arranged on a transmission circuit-side.
SOLUTION: For a high-frequency composite component 10, a two terminal switch 11, an LC filter 12 and a notch filter 13, which constitute a transmission part, are integrated. A fist terminal P1 arranged on an antenna ANT-side is connected to a duplexer DPX, and a second terminal 2 arranged on a transmission circuit Tx-side to a transmission circuit Tx. A wiring connecting the two terminal switch, the LC filter 12 and the notch filter 13, which constitute the transmission part connected between the first terminal P1 and the second terminal P2, can be arranged in the stacked body as a via hole electrode. Thus, the loss in the wiring can be reduced.
