1. A radio frequency front end (RFFE) device comprising:
a plurality of ports each connectable to an antenna;
a first circuit configured to process a first signal for a first operating frequency band included in a first frequency band group;
a second circuit configured to process a second signal for a second operating frequency band included in a second frequency band group;
a diplexer including a first end electrically connected with a first port of the plurality of ports, a second end, and a third end;
a first conductive line connecting the first circuit and a second port of the plurality of ports;
a second conductive line connecting the second circuit and a third port of the plurality of ports;
a first switch; connected between the first conductive line and the second end of the diplexer, the first switch being configured to electrically connect or electrically separate the second end of the diplexer to/from the first circuit and the second port based on a first state of the first switch; and
a second switch; connected between the second conductive line and the third end of the diplexer, the second switch being configured to electrically connect or electrically separate the third end of the diplexer to/from the second circuit and the third port based on a state of the second switch.
