Definitions

  • the invention relates to a YIG filter or a YIG oscillator.
  • YIG band-pass filter or YIG oscillators have at least one resonator, which is preferably spherical and made of a yttrium iron garnet (Y ttrium- I RON G arnet YIG) is prepared.
  • 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 for example from the document US 4,480,238 known.
  • 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 above-mentioned publication is, in particular, the complicated manufacture 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 to provide a YIG filter or YIG oscillator, with coupling lines that are easy to manufacture, insensitive to damage and easy to install.
  • Figure 2 discloses a YIG arrangement according to the preamble of claim 1.
  • Fig. 1A shows in a schematic, perspective view of an embodiment of a YIG bandpass filter 2, which has a base body 3 and in the embodiment, four formed in the base body 3 filter chambers 4 with as many YIG elements 6.
  • the YIG elements 6 are spherically formed from an yttrium-iron garnet, mounted on holders 10, for example by gluing with epoxy resin and electromagnetically coupled by coupling lines 1.
  • the filter chambers 4 are interconnected by slots 5, in which the coupling lines 1 are inserted.
  • two of the filter chambers 4 are identical in the embodiment.
  • the filter chambers 4 denoted by 4b have only the YIG elements 6.
  • the number of filter chambers 4b is not limited to two, but may be one or more so that the total number of filter chambers 4 may be three or more.
  • Fig. 1B shows for ease of understanding the arrangement of the coupling lines 1 and mounted on their holders 10 YIG elements 6 without the surrounding body.
  • the coupling lines 1 are executed in the embodiment in two different forms.
  • the filter chambers 4b interconnecting coupling line 1 is designed as input or output line 1a, while in the embodiment, three further coupling lines 1 are designed as connecting lines 1b.
  • Fig. 1B shows, the coupling lines 1 on tabs 8, which serve on the one hand, the ground connection of the coupling lines 1 in the base body 3 and on the other hand, the fixation of the coupling lines 1 in the slots 5.
  • the contact lugs 8 are rectangular in shape, wherein an edge length of the contact lugs 8 corresponds approximately to the axial thickness of the base body 2.
  • FIGS. 2A and 2B is recognizable, whereby the coupling lines 1 according to Fig. 2B from conventional coupling lines 1 according to FIG Fig. 2A differ.
  • the two embodiments have in common that in each case at least one curved portion 17 is provided, which surrounds a respective YIG element 6 so at least partially, that a center of the YIG element 6 coincides with a center of the curved portion 17. Furthermore, at least one line section 18 is provided.
  • FIG. 2A shown coupling line 1 according to the prior art is bent from a wire.
  • the YIG elements 6 in the in FIGS. 2A and 2B introduced basic body 3, not shown, and then inserted only roughly pre-bent wire in the slots 5.
  • 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 according to Fig. 2B made of a metallic foil by suitable methods such as etching, eroding, cutting, in particular 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
  • the film is made of a copper-beryllium alloy to meet both the requirements of elasticity and strength.
  • the thickness of the film is preferably about 50 microns.
  • the preparation of the coupling lines 1 from the film takes place in several processing steps. First, the film is cleaned and applied on both sides with a positive resist at an alignment accuracy of about 5 microns in a layer thickness of about 5 microns to create a mask. 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 all paint residues and galvanically provided with a gold coating of about 5 microns. After that follows a curing process for example, one hour at 325 ° C. Then the coupling lines can be released from the film carrier 9 and installed.

  • the YIG elements 6 are then aligned relative to the coupling lines 1. This is compared to the prior art simpler and associated with considerably less effort, because the manufacturing accuracy of the present invention designed coupling lines 1 is considerably larger than in manually curved coupling lines. 1
