Definitions

  • the present invention relates to a branching circulator for large high-frequency outputs with a cooled ferrite structure which is arranged in the waveguide branching zone and is exposed there to a static magnetic field.
  • the ferrite structure consists of a plurality of ferrite disks, separated from one another by air gaps and arranged perpendicular to the static magnetic field, which are attached to metal carriers through which a cooling liquid flows.
  • the invention has for its object to provide a circulator of the type mentioned, which is suitable for operation with very high radio frequency power.
  • the circulator By dividing the circulator ferrite into a large number of spheres, a very extensive cooling surface is created, which enables large amounts of heat to be dissipated. Therefore, the circulator can be operated at a very high output without the ferrite material being destroyed by thermal stresses.
  • a dielectric cylinder 5 is inserted in the waveguide branch, which is inserted in grooves 6, 7 in the mutually facing surfaces of the pole pieces.
  • This dielectric cylinder 5 serves to hold several ferrite balls 8 stacked one on top of the other to form a densest packing of balls, so that a cylindrical ferrite ball cluster in contact with the two pole pieces 3 and 4 is formed.
  • the ferrite balls 8 form a very large surface overall, which provides extremely favorable conditions for the dissipation of the heat present in the ferrite balls 8.
  • a coolant flowing around the ferrite balls for. B. gas or a suitable dielectric liquid can easily dissipate very large amounts of heat from the ferrite ball pile.
  • openings 9 and 10 are provided in the pole pieces 3 and 4, through which a gaseous or liquid coolant can penetrate into the dielectric cylinder 5 and escape again from the dielectric cylinder 5 after flowing through the ferrite ball cluster.
  • the dielectric cylinder 5 In order that no coolant from the dielectric cylinder 5 gets into the waveguide arms of the circulator, the dielectric cylinder 5 is sealed with sealing rings 11 and 12 in the grooves 6 and 7 of the pole pieces 3 and 4.
  • the openings 9 and 10 in the pole pieces 3 and 4 pointing into the waveguide branch are dimensioned such that they are impermeable to the high-frequency field in the circulator.
  • the direct contact of the pole pieces 3 and 4 with the ferrite balls 8 creates a very small magnetic resistance for the static magnetic field spreading between the pole pieces.
  • the magnetic field required for the magnetization of the ferrite ball cluster can be applied by a less complex magnet system.
  • FIG. 2 shows a section through a branching circulator using stripline technology.
  • the inner conductor 14 forms, together with the pole shoes 3 and 4 serving as the outer conductor, a waveguide branching which is implemented using stripline technology.
  • this strip conductor branching circulator all parts which correspond to components of the waveguide circulator are provided with the same reference symbols used in FIG. 1.
  • there are two dielectric cylinders filled with ferrite balls one of which dielectric cylinder 5 with the ferrite balls 8 between the top of the inner conductor 14 and the pole piece 3 and the other dielectric cylinder 5 ⁇ with the ferrite balls 8 ⁇ between the bottom of the inner conductor 14 and the pole piece 4 is arranged. So that the coolant can flow from one dielectric cylinder 5 into the other 5 ⁇ , the inner conductor 14 is provided with holes 16.
  • the dielectric cylinders 5 and 5 ⁇ are sealed against the outflow of coolant at the pole pieces 3 and 4 and on the inner conductor 14.
  • the inner conductor 14 can be made of magnetically conductive material in order to keep the magnetic resistance of the arrangement between the pole pieces small.
