Claim 8:
9. The directional coupler according to claim 1,
wherein the second switching circuit is configured to:
connect the second end of the sub-line to the coupling terminal at a different time than when the second switching circuit disconnects the second end of the sub-line from the terminal circuit based on the control signal, and
disconnect the second end of the sub-line from the coupling terminal at a different time than when the second switching circuit connects the second end of the sub-line to the terminal circuit based on the control signal,

wherein the first switching circuit is configured to connect the first end of the sub-line to the coupling terminal at the same time as the second switching circuit connects the second end of the sub-line to the terminal circuit, and
the first switching circuit is configured to connect the first end of the sub-line to the terminal circuit at the same time as the second switching circuit connects the second end of the sub-line to the coupling terminal.
