Abstract (en)
[origin: WO2011076328A1] The broadband directional coupler is used to measure the power of a forward and/or a return high frequency signal on a line. For said purpose the broadband directional coupler comprises a voltage divider, which is connected to an inner conductor (1) of the line. Said voltage divider comprises a first resistor (8), which is connected to an outer conductor of the line. The voltage divider consists of 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 to a first connection of the first resistor (8) and at the same time is connected directly or indirectly to the outer conductor of the line. A voltage to be measured is tapped at the second connection of the second resistor (4) and at the first connection of the third resistor (6).
