<P>PROBLEM TO BE SOLVED: To provide an electronic component capable of securing excellent isolation characteristics. <P>SOLUTION: An electronic component includes: a first circuit 10 connected to a first common end 50 for inputting/outputting a first signal, a second common end 52 for inputting/outputting a second signal with a frequency higher than that of the first signal, and a third common end 54 for connection to an antenna 16; and a second circuit 20 connected to the first circuit 10 in parallel between the first common end 50 and the second common end 52. The third common end 54 is positioned between a low-pass filter (LPF) 12 and a high-pass filter (HPF) 14. The first circuit 10 includes: the LPF 12 for passing the first signal and reflecting the second signal; and the HPF 14 for passing the second signal and reflecting the first signal. The second circuit 20 reflects a first transmission signal and a second transmission signal, passes the partial portions of the first transmission signal and the second transmission signal, and reverses the phases of the partial portions of the first transmission signal and the second transmission signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
