Abstract
Isolation between the first path and second path is increased. A radio frequency module includes a first inductor, a second inductor, a third inductor, and a switch. The first inductor is provided in a first path through which a first communication signal travels. The second inductor is provided in a second path through which a second communication signal travels, the second path being used simultaneously with the first path. The third inductor is provided in a third path through which a third communication signal travels, the third path not being used simultaneously with the first path. The switch is provided between ground and a node in the third path and is connected to the third inductor. The third inductor is arranged between the first inductor and the second inductor.

A radio frequency module comprising:
- a first inductor connected to a first path through which a first communication signal travels;
- a second inductor connected in a second path through which a second communication signal travels, the second communication signal traveling simultaneously with the first communication signal;
- a third inductor connected in a third path through which a third communication signal travels, the third communication signal not traveling simultaneously with the first communication signal;
- and
- a switch connected between the third path and ground, the switch being connected to the third inductor,
- wherein the third inductor is physically arranged on a mounting board between the first inductor and the second inductor.
