ABSTRACT:
A directional coupler provides at least two coupled lines, at least three ports and at least one inductor. A high-frequency signal is transmitted from the first coupled line to the second coupled line. The circuit is constructed in stripline technology. In this context, the second coupled line provides a forward path and a return path, which are connected to a port. An inductor is connected in series to the return path.
