SPLITTER CIRCUIT, FRONT END MODULE, AND OPERATING METHOD THEREOF

A splitter circuit includes: a signal divider configured to split and transmit a first radio frequency (RF) signal received in a first receiving mode in which a first communication scheme and a second communication scheme are simultaneously performed; a first bypass circuit configured to bypass the signal divider to transmit a second RF signal received in a second receiving mode in which the first communication scheme is performed; and a second bypass circuit configured to bypass the signal divider to transmit a third RF signal received in a third receiving mode in which the second communication scheme is performed.
