Abstract

A directional coupler, comprising a first high-frequency line for feeding a first high-frequency signal, a second high-frequency line for feeding a second high-frequency signal, and a coupling line for outputting signals from the first and the second high-frequency lines, wherein the coupling line comprises resistive segments, each comprising a predetermined impedance. Coupling properties and resistive damping and adapting properties can be integrated in the coupling line. A compact and low-cost construction of the directional coupler is thus made possible.
