Abstract:
The present invention heightens isolation between a first path and a second path. This high-frequency module comprises a first inductor (L1), a second inductor (L2), a third inductor (L3), and switches (SW1, SW2). The first inductor (L1) is provided in a first path (T31) through which a first communication signal passes. The second inductor (L2) is provided in a second path (T32) through which a second communication signal passes and which is used simultaneously with the first path (T31). The third inductor (L3) is provided in a third path (T33) through which a third communication signal passes and which is not used simultaneously with the first path (T31). The switches (SW1, SW2) are provided between a node (N1) on the third path (T33) and ground and connected to the third inductor (L3). The third inductor (L3) is positioned between the first inductor (L1) and the second inductor (L2).
