Abstract
A directional coupler includes a main line and a sub-line electromagnetically coupled to each other, a variable termination circuit that is connected to one end of the sub-line and that has a variable impedance, a variable matching circuit that is connected to the other end of the sub-line and that has a variable impedance or a variable attenuator that has a variable attenuation, and a control circuit that controls the impedance of the variable termination circuit and that controls the impedance of the variable matching circuit or the attenuation of the variable attenuator. The control circuit includes a non-volatile memory and controls the impedance of the variable termination circuit in accordance with data stored in the memory.
