<p>The broadband directional coupler is used for measuring the power of a forward and/or a returning high-frequency signal on a line. For this purpose, the broadband directional coupler provides a voltage splitter which is connected to an inner conductor (1) of the line. This voltage splitter provides a first resistor (8) which is connected to an outer conductor of the line. The voltage splitter comprises ohmic resistors, and a first connection of a second resistor (4) is connected to the inner conductor (1) of the line, and a second connection of the second resistor (4) is connected to a first connection of a third resistor (6). A second connection of the third resistor (6) is connected directly or indirectly to a first connection of the first resistor (8) and at the same time to the outer conductor of the line. In this context, a measured voltage is picked up at the second connection of the second resistor (4) or at the first connection of the third resistor (6).</p> |
