Definitions

  • the invention relates to a converter for a satellite antenna.
  • Known converters of this type are e.g. on dish-shaped satellite receiving antennas arranged and usually have a so-called horn, which is at the end of the waveguide is arranged.
  • the microwaves received by the antenna are replaced by the Waveguide passed into the converter and converted there into high frequency.
  • This High frequency is then extracted from the converter e.g. to a satellite receiver guided.
  • the known converters usually have a two-part metallic Housing, the plate-shaped circuit carrier first in the with the waveguide connected lower housing part is used and then through the housing Put on the lid is closed.
  • the high-frequency contact is made by a coaxial line connection, when inserting the circuit carrier with this contacted.
  • the waveguide short circuit is located in the metallic cover.
  • Cavities also form in the lower housing part with components on the circuit carrier electrical circuits. For example, a precisely limited cavity in the lower part of the housing available, the one with corresponding components on the circuit board adjustable cavity forms. Furthermore, there are cavities in the lower housing part Circuit levels, e.g. Filters, amplifiers or the like, available.
  • a converter for a satellite antenna is also known from EP 0 231 422 A2. It A plate is mentioned which is independent of the converter housing and which is part of a Waveguide and microwave circuit modules supporting heat sink forms.
  • the invention has for its object the effort in the production of such Reduce converters and achieve greater flexibility.
  • a arranged in the housing of the converter and out of the housing Removable core module of the converter is provided, which is a cavity element Base element and one between the cavity element and the base element arranged circuit carrier, being formed on the cavity element Cavities with electrical components arranged on the circuit carrier Form circuits.
  • the core module is a self-contained unit, each in a spatially adapted Converter housing is used. It must of course be ensured that the Waveguide input of the housing with the corresponding waveguide input of the Core module corresponds. The same applies to the RF output, which when the Core module is contacted in the housing with the circuit carrier and soldered. On Such core module can thus be manufactured independently of the converter housing to be expelled. Such is a core module adjusted, checked and thus fully functional and can be sold in this state regardless of the housing become. The customer can do that for his needs select specific housing and then choose one Install core module. Changes in the core module take effect no longer depends on the housing design of the converter.
  • the opposite side of the circuit carrier arranged base plate correspondingly shaped and trained stiffening ribs so that the greatest possible The degree of rigidity of the core module is guaranteed.
  • the cavity element, the base element and the Circuit carrier by fasteners, e.g. Screws that are connected to one another and that the cavity element and / or the base element with Guide pins are provided when assembling the three parts in corresponding holes of each engage the opposite part.
  • fasteners e.g. Screws that are connected to one another and that the cavity element and / or the base element with Guide pins are provided when assembling the three parts in corresponding holes of each engage the opposite part.
  • the core module one with the waveguide of the housing has corresponding waveguide, which at its end is short-circuited
  • the base element one with the Corresponding waveguide of the housing Waveguide passage and the cavity element one Has waveguide short circuit.
  • the metallic cavity element and base element Injection molding e.g. made of an aluminum-zinc alloy, are made.
  • Such a construction ensures safe, reliable and inexpensive production method.
  • This design offers the advantage that the core module with simple operations can be inserted into the lower part can, the connection to the waveguide through Tighten the associated fastening screws is guaranteed. Grounding is done as above described by putting on a special one Fixing screw, and the HF connection is made by Solder the correspondingly contacted connecting wire. The housing is then closed by the cover.
  • the core module 10 consists of a Cavity element 11, a base plate 12 and one intermediate circuit carrier 13.
  • the Circuit carrier 12 contains a printed circuit 13a and electronic components 13b, which are not in detail are shown.
  • the circuit carrier 13 forms with im Cavity element 11 arranged cavities 14, 15th electronic circuits. With 14 are for example Cavities referred to using appropriate components adjustable on the circuit carrier 13 Form cavity resonators. 15 denotes others Cavities for circuit levels, e.g. Filter or Amplifier.
  • the core module 10 has one in the upper part Waveguide 16, which consists of a waveguide part 16a in the base plate 12 and a short-circuited part 16b in Cavity element 11 is composed. If the core module in a converter housing is installed (see Fig. 6 further below), this waveguide 16 connects to the Waveguide of the converter housing into one unit.
  • the components 11, 12 and 13 are by screws 17 in the bore 17a with each other to a compact, in itself independent unit connected. This connection is such that the corresponding components are held immovable to each other.
  • Fig. 6 shows a two-part converter housing 20 with a lower housing 20a and a cover part 20b.
  • a core module 21 is used, which consists of a Cavity element 22, a base element 23 and one circuit carrier 24 arranged between them.
  • the Cavity element 22 contains cavities that are associated with corresponding components of the circuit carrier 24 Form circuits.
  • the cavity 22a forms e.g. With corresponding components by a screw 22b adjustable cavity resonator.
  • the core module 21 has also a waveguide 25, which is composed of a waveguide passage 25a in the base member 23 and one short-circuited part 25b in the cavity element 22.
  • Das Housing 20 has an attached on the outside Waveguide 26 having a horn 27 at its outer end having.
  • the waveguide 26 forms with the waveguide 25 and housing parts 20c a common waveguide, the is short-circuited at 25b.
