  • the layer structure of the Kopplersubstrates but also different be executed, for example, with different Substrate thickness or number of layers.
  • the printed circuit board substrate can change for every situation and therefore also different Have quality levels and price ranges.
  • Attenuators 27 also in the form of the mentioned T-circuit instead of an n-circuit formed could be.
  • This T-circuit can also in the for Invention belonging directional coupler according to Figure 5 instead the ⁇ circuit shown there be realized.
  • the coupling lead both in length how width can vary and in different ways Relative position, i. in particular twisting to the underneath the inner conductor can be mounted.
  • the coupling cable does not have to be a stripline be executed. It can also be used as a wire hanger or in the form of a wired component (resistor) be realized.
