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 4):
The directional coupler according to  claim 2 , further comprising:\n a third termination circuit and a fourth termination circuit, the third and fourth termination circuits each connected to the fourth port; and a first switch circuit and a second switch circuit, wherein: the main line is further configured to pass a third signal in a third frequency band and a fourth signal in a fourth frequency band, the third port is further configured to output a third coupled signal corresponding to the third signal and to output a fourth coupled signal corresponding to the fourth signal, the first switch circuit is configured to selectively supply the first coupled signal to the first termination circuit and the third coupled signal to the third termination circuit, and the second switch circuit is configured to selectively supply the second coupled signal to the second termination circuit and the fourth coupled signal to the fourth termination circuit.
