Abstract

See full text

A directional coupler includes a main line, a sub-line, a coupling terminal, a terminal circuit, a first switching circuit, and a second switching circuit. The first switching circuit and the second switching circuit respectively connects the first end and the second end of the sub-line alternately to the coupling terminal and to the terminal circuit. The first switching circuit connects the first end to the coupling terminal at a time that differs from a time at which the first switching circuit disconnects the first end from the terminal circuit. The first switching circuit disconnects the first end from the coupling terminal at a time that differs from a time at which the first switching circuit connects the first end to the terminal circuit.
