Abstract
In a radio-frequency circuit, a first switch is connected to an antenna terminal. A second switch is connected to the first switch and is connected to the antenna terminal via the first switch. A first filter is connected to the first switch without having the second switch interposed therebetween and allows a radio-frequency signal of a first communication band to pass through the first filter. A second filter is connected to the first switch via the second switch and allows a radio-frequency signal of a second communication band to pass through the second filter. The second communication band is higher than the first communication band. The radio-frequency circuit further includes an inductor. The inductor is not connected in series with the first filter and is connected in series with the first switch and the second switch between the first switch and the second switch.
