Abstract:
1. An electronic component comprising: a first circuit that is connected to a first common terminal for inputting and outputting a first signal set including a first transmission signal and a first reception signal having mutually different frequencies, a second common terminal for inputting and outputting a second signal set having a frequency higher than the first signal set and including a second transmission signal and a second reception signal having mutually different frequencies, and a third common terminal for being connected to an antenna; and a second circuit that is connected in parallel to the first circuit between the first common terminal and the second common terminal, wherein the first circuit includes a first filter that transmits the first signal set and reflects the second signal set, and a second filter that transmits the second signal set and reflects the first signal set, the first filter being connected between the first common terminal and the second filter, the second filter being connected between the first filter and the second common terminal, and the third common terminal being located between the first filter and the second filter, and the second circuit includes a first high-pass filter that reflects the first transmission signal and transmits a part of the first transmission signal and the second transmission signal and a first low-pass filter that reflects the second transmission signal and transmits a part of the second transmission signal and the first transmission signal, and inverts a phase of the part of the first transmission signal and a phase of the part of the second transmission signal.
