Description

Die Erfindung bezieht sich auf einen Konverter für eine Satellitenantenne.The invention relates to a converter for a satellite antenna.

Bekannte Konverter dieser Art sind z.B. an schüsselförmigen Satelliten-Empfangsantennen angeordnet und besitzen in der Regel ein sogenanntes Horn, das am Ende des Hohlleiters angeordnet ist. Die von der Antenne empfangenen Mikrowellen werden durch den Hohlleiter in den Konverter geleitet und dort in Hochfrequenz umgewandelt. Diese Hochfrequenz wird sodann aus dem Konverter heraus z.B. zu einem Satellitenempfänger geführt. Die bekannten Konverter besitzen in der Regel ein zweiteiliges metallisches Gehäuse, wobei der plattenförmige Schaltungsträger zunächst in das mit dem Hohlleiter verbundene Gehäuseunterteil eingesetzt wird und wobei sodann das Gehäuse durch Aufsetzen des Deckels verschlossen wird. Der Hochfrequenzkontakt erfolgt durch einen koaxialen Leitungsanschluß, der beim Einsetzen des Schaltungsträgers mit diesem kontaktiert. Der Hohlleiterkurzschluß befindet sich dabei in dem metallischen Deckel. Ferner bilden Hohlräume im Gehäuseunterteil mit Bauteilen auf dem Schaltungsträger elektrische Schaltkreise. So ist z.B. im Gehäuseunterteil ein genau begrenzter Hohlraum vorhanden, der mit entsprechenden Bauteilen auf dem Schaltungsträger einen abgleichbaren Hohlraumresonator bildet. Ferner sind im Gehäuseunterteil Hohlräume für Schaltungsstufen, z.B. Filter, Verstärker oder dergl., vorhanden.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.

Eine derartige Bauweise hat den Nachteil, daß die Gehäusebauteile mit den darin ausgebildeten Hohlräumen genau auf den einzusetzenden Schaltungsträger mit den dort aufgebrachten Bauelementen abgestimmt sein müssen. Bei Änderung des Schaltungsträgers müssen entsprechende Änderungen am Gehäuse vorgenommen werden, wenn dies überhaupt bei der massiven Ausführung des Gehäuses möglich ist. Anderenfalls ist das Gehäuse nicht mehr zu verwenden. Such a construction has the disadvantage that the housing components with the therein trained cavities exactly on the circuit carrier to be used with the there applied components must be coordinated. When changing the circuit board Appropriate changes to the case must be made if this is is even possible with the massive design of the housing. Otherwise it is Housing no longer to be used.

Ein Konverter der genannten Art ist z.B. durch die EP 0 131 633 B1 bekannt geworden, wobei das Gehäuse noch zusätzlich von einer Art Schutzgehäuse umgeben ist.A converter of the type mentioned is e.g. made known by EP 0 131 633 B1, the housing is additionally surrounded by a type of protective housing.

Aus der EP 0 231 422 A2 ist ebenfalls ein Konverter für eine Satellitenantenne bekannt. Es wird eine vom Konvertergehäuse unabhängige Platte erwähnt, die einen Teil eines Hohlleiters und Mikrowellenschaltkreismodule tragende Kühlkörper bildet.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.

Dadurch ergibt sich der Vorteil, daß bei einer evtl. Änderung des Schaltungsträgers das Gehäuse selbst nicht mehr geändert zu werden braucht. Das Kernmodul bildet vielmehr eine in sich abgeschlossene Einheit, die jeweils in ein räumlich entsprechend angepaßtes Konvertergehäuse eingesetzt wird. Dabei muß selbstverständlich gewährleistet sein, daß der Hohlleitereingang des Gehäuses mit dem entsprechenden Hohlleitereingang des Kernmoduls korrespondiert. Gleiches gilt für den HF-Ausgang, der beim Einsetzen des Kernmoduls in das Gehäuse mit dem Schaltungsträger kontaktiert und verlötet wird. Ein derartiges Kernmodul kann somit unabhängig von dem Konvertergehäuse gefertigt und vertrieben werden. Ein derartiges Kernmodul ist abgeglichen, geprüft und somit voll funktionsfähig und kann in diesem Zustand unabhängig vom Gehäuse vertrieben werden. Der Kunde kann somit jeweils das für seine Belange spezifische Gehäuse wählen und dabei dann ein derartiges Kernmodul einbauen. Änderungen im Kernmodul wirken sich nicht mehr auf die Gehäusebauform des Konverters aus.This has the advantage that in the event of a possible change in the circuit carrier Housing itself no longer needs to be changed.

    2. A converter as claimed in claim 1, characterized in that the base element (12, 23) is provided with projecting reinforcement ribs (12a) in the area of the facing edges of the cavities (15, 14).
    3. A converter as claimed in claim 1 or 2, characterized in that the cavity element (11, 22), the base element (12, 23) and the circuit support (13, 24) are connected together by means of fixation elements, for example screws (17), so as to form a unit, and in that the cavity element (11, 22) and/or the base element (12, 23) are provided with guide pins (17b) which, in the assembly of the three parts, engage corresponding holes (17c) in the relevant, facing part.
    4. A converter as claimed in any one of claims 1 to 3, characterized in that the core module (10, 21) has a hollow waveguide (16, 25) which is short-circuited at its end (16b, 25b) and corresponds to the waveguide (26) of the housing (20), the base element (12, 23) having a waveguide passage (16a, 25a) corresponding to the waveguide (26) of the housing (20) and the cavity element (11, 22) having a waveguide short-circuit (16b, 25b).
    5. A converter as claimed in any one of claims 1 to 4, characterized in that fixation screws (18b) engaging holes (18c) are provided in the circumferential proximity of the waveguide (16, 25) of the core module (10, 21), which screws ensure a reliable engagement with, and fixation of the core module to the housing in the area of the waveguide.
    6. A converter as claimed in any one of claims 1 to 5, characterized in that the cavity element (11) and the base element (12) are each formed as lugs (11a, 12a) in the area of the RF terminal of the circuit support (13), and in that the lugs (11a, 12a) and the circuit support (13) are provided with holes for engaging a screw (18a) by which the components (11, 12, 13) are fixed to the housing (20).
    7. A converter as claimed in any one of claims 1 to 6, characterized in that the metallic cavity element (11, 22) and the base element (12, 24) are made of a cast material, for example an aluminium-zinc alloy.
    8. A converter as claimed in any one of claims 1 to 7, characterized in that
      the converter housing has a lower part (20a) and a cover part (20b),
      the lower part (20a) is provided with a waveguide and an RF terminal (20b, 28) and is implemented to accommodate and fix the core module (10, 21), and
      the lower part (20a) and the core module (10, 21) have bearing surfaces (20', 21') which are adapted to each other.
    9. A core module (10, 21) to be built into a converter of a satellite arrangement as claimed in any one of claims 1 to 8, characterized in that the core module (10,21) comprises a cavity element (11, 22), a base element (12, 23) and a circuit support (13, 24) arranged between the cavity element (11,22) and the base element (12,23), while cavities (15, 14) formed on the cavity element (11, 22) constitute electric circuits with components arranged on the circuit support (13, 24).
