1. A radio-frequency module comprising:
a first signal path and a second signal path each configured to pass signals in a first communication band;
an antenna terminal;
a first matching circuit in the first signal path, and a second matching circuit in the second signal path; and
a switching circuit configured to selectively connect the first signal path and/or the second signal path to a common terminal, wherein:
the common terminal is electrically coupled to the antenna terminal,
the switching circuit is configured to connect the first signal path to the common terminal when communications with the radio-frequency module only employ the first communication band,
the switching circuit is configured to connect the second signal path to the common terminal when communications with the radio-frequency module employ both the first communication band and a second communication band, the second communication band being different than the first communication band.
