Patent ID: 7026887

Claim:
A high-frequency composite part for controlling the connection between a transmitting circuit and an antenna, and the connection between a receiving circuit and said antenna comprising: a plurality of filter circuits having different passbands; an amplifier circuit comprising a transistor, an input terminal, and an output terminal; an input-matching circuit connected to the input terminal of said amplifier circuit; an output-matching circuit connected to the output terminal of said amplifier circuit; a phase-shifting circuit controlling the phase angle of a high-frequency signal connected to said output-matching circuit; a high-frequency switch circuit; said filter circuits each comprising an inductor and a capacitor; said input-matching circuit and said output-matching circuit each comprising an inductor and a capacitor; said phase-shifting circuit comprising a distributed constant line; and said high-frequency switch circuit comprising a diode and an inductor, wherein said amplifier circuit, said input-matching circuit, said output-matching circuit, said phase-shifting circuit, said high-frequency switch circuit, and at least parts of inductors and capacitors of said filter circuits are integrated in a multi-layered module laminated by a plurality of dielectric layers and electrode patterns formed thereon, wherein said distributed constant line constituting said phase-shifting circuit are formed by said electrode patterns, and chips of the other parts of inductors and capacitors, said diode and said transistor are mounted on said multi-layered module, and wherein said electrode patterns are led to side surfaces of said multi-layered module to connect with edge terminals formed on the side surfaces thereof so as to enable surface mounting.
