Abstract
A switch module selects one of a CA mode in which first and second frequency bands are used simultaneously and a non-CA mode in which only one of the first and second frequency bands is used. The switch module includes a first signal path propagating the first frequency band therethrough, a second signal path propagating the second frequency band therethrough, a third signal path simultaneously propagating the first and second frequency bands therethrough, a switch circuit, and a variable adjuster. The switch circuit switches the connection between an antenna device and one of the three signal paths. The variable adjuster adjusts a variable matching circuit for the third signal path when the non-CA mode is selected or adjusts a variable matching circuit for the first signal path or that for the second signal path when the CA mode is selected.
