Definitions

  • the input conductor part and the output conductor part may have a special form (in particular comprising asymmetric sections with respect to the mirror plane, for example of open stub-like type) in order to adapt to the impedance level in the area of the unit cell conductor parts.
  • impedance transformers can be used to match in particular a 50 Ohms input/output impedance.
  • the inventive filter device is contacted via the input conductor part and the output conductor part, typically with an input contact line and an output contact leading through an opening of the grounded frame structure (shielding) each.
