Claim 10:
11. A radio frequency module 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 to pass 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 or simultaneously connected to the second common terminal;
a power amplifier that is connected to the first terminal;
a low-noise amplifier that is connected to the second terminal; and
a mounting substrate that has a first main surface and a second main surface that face each other,
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,
wherein the power amplifier is mounted on the first main surface of the mounting substrate, and
wherein the low-noise amplifier, the first switch, and the second switch are mounted on the second main surface of the mounting substrate.
