Power distributing and synthesizing device and mobile communication equipment using same

A power distributing and synthesizing device, comprising:

• a laminated body formed by a plurality of laminated dielectric layers;
• strip line electrodes provided within said laminated body and forming first and second transmission lines;
• first and second ground electrodes provided within said laminated body, said first ground electrode being provided adjacent to a bottom surface of said laminated body;
• via hole electrodes provided within said laminated body;
• a synthesis terminal constituted of the connection portion between one end of said first transmission line and one end of said second transmission line;
• a first distribution terminal constituted of the other end of said first transmission line;
• a second distribution terminal constituted of the other end of said second transmission line;
• a resistor connected between said first distribution terminal and said second distribution terminal;
• and
• at least one LC serial resonator comprising an inductor and a capacitor, wherein:
• at least one terminal among said synthesis terminal, said first distribution terminal, and said second distribution terminal is connected to a ground via said at least one LC serial resonator,
• said inductor is formed of at least one of said strip line electrodes and said via hole electrodes,
• said capacitor of the at least one LC serial resonator is generated between a capacitor electrode and the first ground electrode, the capacitor electrode being opposed to the first ground electrode, and
• the second ground electrode is provided between the strip line electrodes and the capacitor electrode.
