Definitions

  • the invention relates to coupling lines for use in a YIG bandpass filter or a YIG oscillator according to the preamble of claim 1 and a method for producing such coupling lines, which are suitable for use in a YIG bandpass filter or a YIG oscillator, according to the preamble of claim 11.
  • YIG bandpass filters or YIG oscillators have at least one resonator, which is preferably spherical and made of an yttrium iron garnet (Yttrium-Iron-Garnet YIG).
  • the Resonator Brady is mediated by coupling lines, which must be designed and arranged so that the center of the resonator and the center of the bending radius of a coupling line match exactly.
  • a YIG bandpass filter with correspondingly formed coupling lines is known, for example, from the publication US Pat. No. 4,480,238.
  • the tunable YIG bandpass filter in this case has a base body, which slots for receiving isolated platelets having at one edge a conductive coating which serves as coupling lines comprises. Furthermore, filter chambers are provided for receiving the YIG elements. The platelets are placed over the YIG elements in the slots so that the YIG elements are arranged in indentations in the edges provided with the conductive coating. The YIG elements and the plates are fixed in fixed positions.
  • a disadvantage of the YIG bandpass filter known from the cited document is, in particular, the complicated production of the platelets forming the coupling lines.
  • the serving as a carrier insulator must first be appropriately shaped and then provided with the conductive coating. This is expensive and prone to jeopardy because the coating is sensitive to damage due to the small layer thickness.
  • Object of the present invention is therefore to provide coupling lines that are easy to manufacture, insensitive to damage and easy to install, and to provide a method for producing such coupling lines.
  • the object is achieved with respect to the coupling lines by the characterizing features of claim 1, with respect to the method by the characterizing features of claim 11 and with respect to a film carrier for the coupling lines by the characterizing features of claim 19.

  • the YIG elements 6 are formed spherically from an yttrium-iron garnet, mounted on holders 10, for example, by gluing with epoxy resin and electromagnetically coupled by coupling lines 1.

  • the coupling lines 1 are executed in the embodiment in two different forms.
  • the filter chambers 4b interconnecting coupling line 1 is designed as an input or output line Ia, while in the embodiment, three further coupling lines 1 are designed as connecting lines Ib.

  • a measurement of the degree of coupling results where the coupling line 1 still needs to be bent. This is done manually by means of a suitable tool. Thereafter must be checked again and readjusted. For this purpose, each time the YIG filter 2 or YIG oscillator must be opened and then reassembled to make the measurement. The method is thus extremely complicated and often even leads to the fact that the workpiece must be completely discarded after several iterations, because no satisfactory coupling is achieved.
  • the inventively designed coupling lines 1 as shown in FIG. 2B made of a metallic foil 7 by suitable methods such as etching, eroding, cutting, especially laser cutting or water jet cutting and / or punching and assembled. Thereafter, the correct positioning of the YIG elements 6 takes place relative to the coupling lines. 1

Thereafter, the preparation of the coupling lines 1, for example, by spray etching with iron chloride. (FeCl 3). Subsequently, the liberated in the form of a carrier 9 with a predetermined number of coupling lines 1 of lacquer residues and galvanically provided with a gold coating of about 5 microns.
