Abstract
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.
Claims20
A splitter circuit, comprising:
- 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.
A front end module, comprising:
- a first switch configured to switch a received radio frequency (RF) signal input from an antenna;
- an amplifier configured to amplify the received RF signal;
- and
- a splitter circuit configured to split and transmit a first signal output from the amplifier,
- wherein the splitter circuit includes:
- a first bypass circuit configured to not split the first signal in a first receiving mode in which a first communication scheme is performed and transmit the first signal to a first output terminal;
- and
- a second bypass circuit configured to not split the first signal in a second receiving mode in which a second communication scheme is performed and transmit the first signal to a second output terminal.
An operating method of a splitter circuit configured to split a received RF signal, the operating method comprising:
- splitting the received RF signal into a first split signal and a second split signal in a first receiving mode in which a first communication scheme and a second communication scheme are simultaneously performed;
- providing a first path that does not split the received RF signal in a second receiving mode in which only the first communication scheme is performed and bypasses the received RF signal;
- and
- providing a second path that does not split the received RF signal in a third receiving mode in which only the second communication scheme is performed and bypasses the received RF signal.
