HIGH FREQUENCY COMPOSITE COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a high frequency composite component used for a high frequency band such as a microwave and formed of a single module comprising a diplexer and a surface acoustic wave (SAW) duplexer in a front end portion for processing a high frequency signal between a transmitting/receiving unit and an antenna of a high frequency circuit of a dual band mobile communication terminal thereby improving characteristics such as reducing insertion loss and satisfying the miniaturization of the mobile communication terminal.

SOLUTION: The diplexer 21 is formed of a conductive pattern on pattern dielectric sheets of a laminated structure, the SAW duplexer 22 includes two SAW filters mounted on a cavity of the laminated structure and a phase shifting device formed as a conductive pattern on a dielectric sheet of the laminated structure.
