Abstract
A directional coupler circuit includes a signal line disposed between a first terminal and a second terminal; a coupling line comprising a first end terminal and a second end terminal, and disposed to be coupled to the signal line; a switching circuit connecting the first end terminal and a coupling port to each other to extract a first coupling signal in a first coupling mode, and connecting the second end terminal and the coupling port to extract a second coupling signal in a second coupling mode; and a phase compensating circuit configured to compensate for a phase difference between the coupling port and a first isolation port in the first coupling mode, or compensate for a phase difference between the coupling port and a second isolation port in the second coupling mode.
