<P>PROBLEM TO BE SOLVED: To provide a demultiplexing circuit which reduces an unnecessary band while suppressing complication and enlargement of the circuit and an increase in insertion loss. <P>SOLUTION: The demultiplexing circuit includes a common terminal, a low-frequency terminal, a high-frequency terminal, a low-frequency side path having a low-frequency filter provided between the common terminal and the low-frequency terminal, and a high-frequency side path having a high-frequency filter provided between the common terminal and the high-frequency terminal. The demultiplexing circuit is characterized in that parasitic capacitance formed on the common terminal side is used as a capacitor for suppressing harmonics. <P>COPYRIGHT: (C)2013,JPO&INPIT |
