Definitions

  • the invention relates to a converter for a satellite antenna with a housing accommodating a circuit carrier, which has a waveguide that can be connected to the circuit carrier and an RF output that can be connected to the circuit carrier.
  • Known converters of this type are arranged, for example, on dish-shaped satellite receiving antennas and generally have a so-called horn, which is arranged at the end of the waveguide.
  • the microwaves received by the antenna are passed through the waveguide into the converter, where they are converted into high frequency.
  • This high frequency is then passed out of the converter, for example to a satellite receiver.
  • the known converters generally have a two-part metallic housing, the plate-shaped circuit carrier first being inserted into the lower housing part connected to the waveguide, and then the housing being closed by fitting the cover.
  • the high-frequency contact takes place through a coaxial line connection which contacts the circuit carrier when it is inserted.
  • the waveguide short circuit is located in the metallic cover. Furthermore, cavities in the lower housing part with components on the circuit carrier form electrical circuits.
  • cavities for circuit stages for example filters, amplifiers or the like, are present in the lower housing part.
  • Such a construction has the disadvantage that the housing components with the cavities formed therein have to be matched exactly to the circuit carrier to be used with the components applied there. If the circuit carrier is changed, corresponding changes must be made to the housing, if this is possible at all in the massive version of the housing. Otherwise the housing can no longer be used.
  • a converter of the type mentioned is e.g. become known from EP 0 131 633 B1, the housing being additionally surrounded by a type of protective housing.
  • the invention has for its object to reduce the effort in the manufacture of such converters and to achieve greater flexibility.
  • the circuit carrier with adapted metallic components forms an independent, fully functional core module which can be built into the housing.
  • the core module forms a self-contained unit that is inserted into a spatially adapted converter housing. It must of course be ensured that the waveguide input of the housing corresponds to the corresponding waveguide input of the core module. The same applies to the HF output, which is contacted and soldered to the circuit carrier when the core module is inserted into the housing.
  • Such a core module can thus be manufactured and sold independently of the converter housing.
  • the customer can therefore choose the housing that is specific to their needs and then install such a core module. Changes in the core module no longer affect the housing design of the converter.
  • the cavities arranged in the housing of the converter itself in the previously known types are now arranged according to the invention on the cavity element which is removably arranged with the core module, corresponding circuits being formed in the assembled state with the components of the circuit carrier.
  • the base plate arranged on the opposite side of the circuit carrier has appropriately shaped and designed stiffening ribs, so that the greatest possible degree of rigidity of the core module is ensured.
  • the cavity element, the base element and the circuit carrier are connected to one another by fastening elements, for example screws, and that the cavity element and / or the base element with Guide pins are provided which engage in the corresponding bores of the opposite part when the three parts are assembled.
  • fastening elements for example screws
  • the cavity element and / or the base element with Guide pins are provided which engage in the corresponding bores of the opposite part when the three parts are assembled.
  • the core module has a waveguide which corresponds to the waveguide of the housing and which is short-circuited at its end, the base element having a waveguide passage corresponding to the waveguide of the housing and the hollow element having a waveguide short-circuit.
  • fastening screws are provided in a further embodiment of the invention in the vicinity of the circumference of the waveguide of the core module, which ensure reliable installation and fastening of the core module in the region of the waveguide with the housing.
  • the cavity element and the base element in the RF connection area of the circuit carrier are each designed as tongues and that the tongues and the circuit carrier are provided with bores for receiving a screw, whereby the components are fastened to the housing.
  • the metallic cavity element and base element made of injection molding e.g. are made of an aluminum-zinc alloy.
  • Such a construction ensures a safe, reliable and inexpensive method of manufacture.
  • This design offers the advantage that the core module can be inserted into the lower part in a simple manner, the connection to the waveguide being ensured by tightening the associated fastening screws.
  • the earthing is done by tightening a special fastening screw, and the HF connection is made by soldering 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 a circuit carrier 13 arranged between them.
  • the circuit carrier 12 contains a printed circuit 13a and electronic components 13b, which are not shown in detail.
  • the circuit carrier 13 forms, with the cavities 14, 15 arranged in the cavity element 11, electronic circuits.
  • Numbers 14 denote, for example, cavities which form cavity resonators which can be compared with corresponding components on the circuit carrier 13.
  • 15 denotes further cavities for circuit stages, for example filters or amplifiers.
  • the core module 10 has a waveguide 16 in the upper part, which is composed of a waveguide part 16a in the base plate 12 and a short-circuited part 16b in the cavity element 11. If the core module is installed in a converter housing (see FIG. 6 below), this waveguide 16 connects to the waveguide of the converter housing to form a unit.
  • the components 11, 12 and 13 are connected to one another by screws 17 in the bore 17a to form a compact, self-contained unit. This connection is such that the components corresponding to one another are held immovably to one another.
  • the components 11, 12 are each formed in the RF connection corner of the circuit carrier 13 as tongues 11a, 12a, which are provided with bores for receiving a screw 18a for attachment to the housing 20. Screws 18b which are guided in bores 18c in the edge region of the waveguide 16 are also used to fasten the core module 10 (11, 12, 13) to the housing 20.
  • the circuit carrier 13 contains an opening 13c in the region of the tongues 11a, 12a for the passage of a connecting wire 19 for the HF derivation.
  • the circuit carrier 13 is designed to be electrically conductive on its underside 13d in order to make an earth contact with the converter housing during assembly.
  • 17b denotes pins which engage in bores 17c and possibly also in housing bores when parts 11, 12, 13 are joined together.
  • the antenna voltage is tapped on wires 30. With 12a projecting stiffening ribs on the base part 12 are designated.
  • FIG. 6 shows a two-part converter housing 20 with a lower housing 20a and a cover part 20b.
  • a core module 21 is inserted into this converter housing 20, which consists of a cavity element 22, a base element 23 and a circuit carrier 24 arranged between them.
  • the cavity element 22 contains cavities that are associated with corresponding components of the circuit carrier form 24 circuits.
  • the cavity 22a forms, for example with corresponding components, a cavity resonator that can be adjusted by a screw 22b.
  • the core module 21 also has a waveguide 25, which is composed of a waveguide passage 25a in the base element 23 and a short-circuited part 25b in the cavity element 22.
  • the housing 20 has an attached waveguide 26 on the outside, which has a horn 27 at its outer end.
  • the waveguide 26 forms with the waveguide 25 and housing parts 20c a common waveguide which is short-circuited at 25b.
  • an RF connection is designated, which is connected via a wire 29 to the circuit carrier 24.
