Abstract:
A directional coupler includes a main line through which a first signal in a first frequency band and a second signal in a second frequency band pass from a first port to a second port, a sub-line electromagnetically coupled to the main line and having a third port and a fourth port, the third port outputting a first coupled signal corresponding to the first signal and a second coupled signal corresponding to the second signal, a first termination circuit connected to the fourth port and used in outputting the first coupled signal, a second termination circuit connected to the fourth port and used in outputting the second coupled signal, and a first filter circuit disposed between the fourth port and the first termination circuit, wherein the first filter circuit has frequency characteristics allowing the first coupled signal to pass therethrough and attenuating the second coupled signal.

Claim (Index 9):
The directional coupler according to  claim 7 , further comprising:\n a third switch circuit configured to selectively connect each of the first filter circuit and the third filter circuit to one of the first termination circuit and the first output port; and a fourth switch circuit configured to selectively connect each of the second filter circuit and the fourth filter circuit to one of the second termination circuit and the second output port, wherein: the fourth port is configured to output a first reflected coupled signal corresponding to a reflected signal of the first signal and to output a second reflected coupled signal corresponding to a reflected signal of the second signal, when the directional coupler is configured to output the first coupled signal or the second coupled signal, the third switch circuit connects an output of the first filter circuit to the first termination circuit and an output of the third filter circuit to the first output port, and the fourth switch circuit connects an output of the second filter circuit to the second termination circuit and an output of the fourth filter circuit to the second output port, and when the directional coupler is configured to output the first reflected coupled signal or the second reflected coupled signal, the third switch circuit connects the output of the first filter circuit to the first output port and the output of the third filter circuit to the first termination circuit, and the fourth switch circuit connects the output of the second filter circuit to the second output port and the output of the fourth filter circuit to the second termination circuit.
