Original Abstract Submitted

A radio-frequency module includes a first switch, a first filter, second filters, a power amplifier, and a low-noise amplifier. The first switch has a first terminal, a second terminal, and a third terminal. The first terminal is coupled to an antenna terminal. The first filter is coupled to the second terminal. The second filters are coupled to the third terminal. The first filter includes a common filter circuit and an additional filter circuit. The additional filter circuit is coupled between the power amplifier and the common filter circuit. The low-noise amplifier is coupled to a path that branches off from a path connecting between the common filter circuit and the additional filter circuit. The common filter circuit is coupled between the additional filter circuit and the first switch.
