Zusammenfassung:A radio frequency module that includes a first antenna terminal, a second antenna terminal, a TDD filter, a transmission filter, a filter, and a first switch. The first switch has a first common terminal, a second common terminal, a first terminal, a second terminal, and a third terminal. The filter is connected to the first terminal, the TDD filter is connected to the second terminal, and the transmission filter is connected to the third terminal. The first switch is capable of switching between a first connection state and a second connection state. The first connection state connects the first common terminal to the first terminal and the first common terminal to the second terminal simultaneously. The second connection state connects the first common terminal to the first terminal, the first common terminal to the second terminal, and the second common terminal to the third terminal simultaneously.
