| 摘要 |
The invention relates to a directional coupler (1), comprising a first high-frequency line (2) for feeding a first high-frequency signal, a second high-frequency line (3) for feeding a second high-frequency signal, and a coupling line (4) for outputting signals from the first and the second high-frequency lines (2, 3), wherein the coupling line (4) comprises resistive segments (5a-5c, 15a-15c, 25a-25c, 35a-35c, 45a), each comprising a predetermined impedance. Coupling properties and resistive damping and adapting properties can be integrated in the coupling line (4). A compact and low-cost construction of the directional coupler (1) is thus made possible.
