Claim 0:
1. A radio frequency circuit comprising:
a filter that has a first input-output terminal, a second input-output terminal, and a ground terminal, that is configured to pass a transmission signal in a predetermined frequency band from the second input-output terminal to the first input-output terminal, and that is configured to pass a reception signal in the predetermined frequency band from the first input-output terminal to the second input-output terminal;
a first switch that has a first common terminal that is connected to the second input-output terminal, a first terminal, and a second terminal, the first and second terminals being exclusively connectable to the first common terminal; and
a second switch that has a second common terminal that is connected to the ground terminal, a first selection terminal, and a second selection terminal, the first and second selection terminals being exclusively connected to the second common terminal,
wherein only the first selection terminal or the second selection terminal is connected to ground with a reactive element interposed therebetween, or
wherein the first selection terminal is connected to ground with a first reactive element interposed therebetween, and the second selection terminal is connected to ground with a second reactive element interposed therebetween, the second reactive element having a reactance value that differs from a reactance value of the first reactive element.
