Definitions

  • the invention relates to a base body for a YIG bandpass filter or a YIG oscillator according to the preamble of claim 1.
  • YIG bandpass filters or YIG oscillators have at least one YIG element, which is preferably spherical and made of an yttrium iron garnet (Yttrium-Iron-Garnet YIG).
  • the Resonator Brady is mediated by means of coupling loops, which must be designed and arranged so that the center of the YIG element and the center of the bending radius of a coupling loop match exactly.
  • a YIG bandpass filter with appropriately trained coupling loops is for example from the US 4,480,238 known.
  • the tunable YIG bandpass filter in this case has a base body, which comprises slots for receiving insulated plates, which have at one edge a conductive coating, which serves as a coupling line. 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 known from practice YIG bandpass filters with wire loops as coupling elements is in particular that the production of the YIG filter by the manual bending of the coupling loops consuming, complicated and associated with a high rejection rate
  • Object of the present invention is therefore to provide a base for a YIG filter or a YIG oscillator, which allows the use of prefabricated coupling loops with reproducible high mounting precision.
  • Fig. 1 and 2 show in a schematic, perspective view or a schematic plan view of an embodiment of a YIG bandpass filter 1, which has a base body 2 and in the embodiment four in the base body 2 formed filter chambers 3 with as many YIG elements 4.
  • the YIG elements 4 are spherically formed from an yttrium-iron garnet and electromagnetically coupled by coupling loops 5.
  • the filter chambers 3 are interconnected by channels 6, in which the coupling loops 5 are inserted.
  • the channels have enough distance to the respective coupling loops to form with these line systems.
  • the number of filter chambers 3 is not limited to four, but may be less or more.
  • the channels 6 do not extend in full length through the entire axial extension of the main body 2. Between the filter chambers 3, the channels 6 are formed only up to a certain depth, which is slightly more than the insertion depth of the coupling lines 5.
  • the FIGS. 3A and 3B illustrate this by two representations of the body 2 in opposite directions. In Fig. 3A the bottom 7 of the main body 2 is shown while Fig. 3B the top 8 shows. In Fig. 3A Accordingly, the channels 6 are not visible between the filter chambers 3, since they do not extend through the entire axial thickness of the base body 2, while in Fig. 3B are visible on the surface 8.
  • slots 11 extending radially outwards with blind ends are formed over the entire axial thickness of the main body.
  • slot 12 between the resonators at the input and output of the filter.
  • the Recesses 9 thereby fulfill the task, on the one hand to receive the coupling loops 5 and at the same time to allow the supply of solder mass during the assembly of the coupling loops 5.
  • the coupling loops 5 In order to enable the simple assembly of the coupling loops 5, they are first produced by means of a suitable method such as etching, laser cutting or eroding from a film with constant accuracy and reproducibility.
  • the coupling loops 5 have to facilitate assembly to contact lugs 10, which are preferably formed integrally with the coupling loops 5 and preferably rectangular in shape, wherein an edge length of the contact lugs 10 corresponds approximately to the axial thickness of the base body 2.
  • the introduced into the recesses 9 solder mass includes the contact lugs 10 so that on the one hand, a reliable fixation of the coupling loops 5 in the recesses 9 and on the other hand a conductive connection between the base body 2 and the coupling loops 5 takes place.
  • the solder mass also flows down to the mounting pad and thus also includes the bottom and top flush with the top 8 and the bottom 7 of the body 2, so that after assembly there is a smooth component, which without risk of snagging or Loss of the coupling loops 5 can be further processed.
