Ces agencements connus présentant l'inconvénient d'avoir une structure complexe et d'être d'un coût de fabrication élevé.These known arrangements have the disadvantage of having a complex structure and being of a high manufacturing cost.

L'invention a pour but de proposer un agencement de convertisseur qui pallie les inconvénients de l'état de la technique.The object of the invention is to propose a converter arrangement which overcomes the drawbacks of the state of the art.

Pour atteindre ce but, l'agencement selon l'invention est caractérisé en ce que les parties de sortie des deux dispositifs convertisseurs sont réalisées sous forme d'une pièce monobloc tandis que les parties d'entrée sont séparées et montées sélectivement orientables sur la pièce monobloc, l'agencement étant monté rotatif autour d'un axe parallèle aux deux parties d'entrée, selon la revendication 1.To achieve this purpose, the arrangement according to the invention is characterized in that the output portions of the two converter devices are formed as a single piece while the input parts are separated and mounted selectively orientable on the part. monobloc, the arrangement being rotatably mounted about an axis parallel to the two input parts, according to claim 1.

Selon une caractéristique de l'invention, chaque partie d'entrée comporte des moyens de conversion des signaux à polarisation linéaire reçus en signaux à polarisation circulaire et la partie de sortie de chaque dispositif comporte des moyens de conversion des signaux à polarisation circulaire en signaux à polarisation linéaire.According to one characteristic of the invention, each input part comprises means for converting the linearly polarized signals received into circularly polarized signals and the output part of each device comprises means for converting the circularly polarized signals into digital signals. linear polarization.

Selon une autre caractéristique de l'invention, chaque partie d'entrée comporte un élément guide d'ondes monté sur un élément guide d'ondes de sortie solidaire de la pièce monobloc, en alignement axial avec et angulairement mobile par rapport à celui-ci.According to another characteristic of the invention, each input part comprises a waveguide element mounted on an output waveguide element integral with the one-piece part, in axial alignment with and angularly movable relative thereto. .

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemples illustrant un mode de réalisation de l'invention et sur lesquels :

La figure 1 montre une antenne parabolique 1 équipée d'un agencement de source à faible bruit 2 selon la présente invention. Cet agencement est conçu pour permettre la réception des signaux à polarisation linéaire, horizontale ou verticale, émis par deux satellites géostationnaires d'une distance l'un de l'autre relativement faible. Chaque satellite peut émettre sur deux bandes de fréquence, une bande basse allant de 10,7 GHz à 11,7 GHz et une bande haute allant de 11,7 GHz à 12,75 GHz. L'agencement convertisseur convertit la bande totale de 11,7 à 12,75 GHz en une bande de 0,950 à 2,150 GHz. Les signaux ainsi convertis sont transmis à un récepteur 3. Celui-ci peut donc recevoir des signaux émis par le satellite A1 (non représenté), à polarisation linéaire horizontale ou verticale, se situant soit dans la bande basse, soit dans la bande haute et des signaux en provenance du deuxième satellite A2 (non représenté), à polarisation linéaire horizontale ou verticale et se trouvant soit dans la bande basse soit dans la bande haute. Lorsque l'utilisateur souhaite sélectionner un programme, il actionne un organe sélecteur du récepteur 3 qui assure alors la sélection du satellite A1 ou A2, la polarisation verticale ou horizontale et de la bande basse ou haute par envoi d'un signal de sélection approprié, respectivement SA, SP et SB. Ces signaux de sélection commandent des commutateurs prévus dans l'agencement, comme on le verra lors de la description de la structure de celui-ci.Figure 1 shows a parabolic antenna 1 equipped with a low noise source arrangement 2 according to the present invention. This arrangement is designed to allow the reception of linear, horizontal or vertical, emitted by two geostationary satellites from a relatively small distance from each other. Each satellite may transmit on two frequency bands, a low band from 10.7 GHz to 11.7 GHz and a high band from 11.7 GHz to 12.75 GHz. The converter arrangement converts the total band from 11.7 to 12.75 GHz into a band of 0.950 to 2.150 GHz. The signals thus converted are transmitted to a receiver 3. This receiver can therefore receive signals emitted by the A1 satellite (not shown), with horizontal or vertical linear polarization, situated either in the low band or in the high band and signals from the second A2 satellite (not shown), with horizontal or vertical linear polarization and located either in the low band or in the high band. When the user wishes to select a program, he actuates a selector member of the receiver 3 which then selects the satellite A1 or A2, the vertical or horizontal polarization and the low or high band by sending an appropriate selection signal, respectively SA, SP and SB. These selection signals control switches provided in the arrangement, as will be seen when describing the structure thereof.

Comme on le voit sur les figures 2 et 3, l'agencement comporte deux convertisseurs à faible bruit 5 et 6, communément appelés dans la technique LNB (Low Noire Bloc) comportant chacun un guide d'ondes respectivement 7 et 8. Chaque guide d'ondes 7 et 8 comporte un élément guide d'ondes d'entrée 9 formant source et un élément guide d'ondes de sortie 10. Les éléments 10 sont montés fixes sur un boîtier de support 12 qui loge le dispositif électronique monté sur une plaque à circuit imprimé 13. C'est la sortie 14 de cette plaque qui est reliée par un câble coaxial 15 au récepteur 3.As can be seen in FIGS. 2 and 3, the arrangement comprises two low-noise converters 5 and 6, commonly known in the LNB (Low Black Bloc) technique, each comprising a waveguide 7 and 8, respectively. 7 and 8 comprises an input waveguide element 9 and an output waveguide element 10. The elements 10 are fixedly mounted on a support housing 12 which houses the electronic device mounted on a plate 13. This is the output 14 of this plate which is connected by a coaxial cable 15 to the receiver 3.

Chaque élément guide d'ondes d'entrée 9 est axialement aligné avec l'élément de sortie 10 et est monté angulairement mobile sur celui-ci. A cette fin, l'élément 10 porte à son extrémité avant une bride 17 et l'extrémité arrière de l'élément 9 est pourvue d'une bride 18. L'assemblage des deux éléments se fait par liaison des deux brides 17, 18 à l'aide de vis 19. Pour assurer la rotation de l'élément de guide d'ondes 9 par rapport à l'élément de sortie 10, selon un angle prédéterminé, l'ouverture de passage des vis 19 est réalisée dans la bride 18 sous forme d'un trou oblong arqué 20.Each input waveguide element 9 is axially aligned with the output member 10 and is angularly movably mounted thereon. To this end, the element 10 carries at its front end a flange 17 and the rear end of the element 9 is provided with a flange 18. The assembly of the two elements is done by connecting the two flanges 17, 18 by means of screws 19. To rotate the waveguide element 9 with respect to the output element 10, according to a predetermined angle, the opening of passage of the screws 19 is made in the flange 18 in the form of an arcuate oblong hole 20.

Chaque élément guide d'ondes d'entrée 9 est pourvu de moyens convertisseurs de signaux à polarisation linéaire verticale ou horizontale en signaux de polarisation circulaire dans l'un ou l'autre sens de rotation. Ces moyens convertisseurs sont formés par une lame de Téflon 22 qui s'étend à l'intérieur de l'élément 9 dans la direction longitudinale de celui-ci. La lame 22 est fixée diagonalement dans l'élément 9 en s'engageant par ses bords longitudinaux dans des rainures 23 dans la face interne de l'élément 9. Les extrémités de la lame de Téflon 22 sont configurées en queue d'aronde. Les deux éléments guide d'ondes de sortie 10 logent également une lame de Téflon indiquée en 25 qui présente sensiblement la même forme que la lame 22 et est montée de la même manière mais angulairement décalée de 90°. Cette lame 25 constitue un moyen convertisseur des signaux à polarisation circulaire produit par l'élément d'ondes 9 en signaux à polarisation linéaire verticale ou horizontale. A l'extrémité arrière de l'élément guide d'ondes de sortie 10 sont prévus, comme on le voit plus clairement sur la figure 4, deux éléments d'antenne 27, 28 réalisés sous forme de pointes faisant saillie radialement vers l'intérieur de la face intérieure de l'élément 10, tout en étant angulairement décalés de 90°. L'élément 27 s'étend horizontalement et sert à la réception des signaux à polarisation horizontale tandis que l'élément 28 est orienté verticalement pour la réception des signaux à polarisation verticale.Each input waveguide element 9 is provided with vertical or horizontal linear polarization signal converter means in circular polarization signals in either direction of rotation. These converter means are formed by a Teflon blade 22 which extends inside the element 9 in the longitudinal direction thereof. The blade 22 is diagonally fixed in the element 9 by engaging with its longitudinal edges in grooves 23 in the inner face of the element 9. The ends of the Teflon blade 22 are configured dovetail. The two output waveguide elements 10 also house a Teflon blade indicated at 25 which has substantially the same shape as the blade 22 and is mounted in the same manner but angularly offset by 90 °. This plate 25 is a means for converting the circularly polarized signals produced by the wave element 9 into vertical or horizontal linear polarization signals. At the rear end of the output waveguide element 10 are provided, as is more clearly seen in FIG. 4, two antenna elements 27, 28 in the form of radially inwardly projecting points. of the inner face of the element 10, while being angularly offset by 90 °. The element 27 extends horizontally and serves to receive the horizontally polarized signals while the element 28 is oriented vertically for the reception of the vertically polarized signals.

En se référant à la figure 3, on constate que les éléments d'antenne 27 et 28 de chaque dispositif de convertisseur 5, 6 sont reliés par l'intermédiaire d'un amplificateur 30 à une entrée d'un commutateur de polarisation 32 dont la sortie est reliée par l'intermédiaire d'un amplificateur 33 à une des deux entrées d'un commutateur de position 35. Un amplificateur 36 relie la sortie de ce dernier à l'entrée d'un diviseur 37 qui comporte un premier circuit de sortie comprenant un mélangeur 38 auquel est associé un oscillateur local 39 et un amplificateur 40 et un deuxième circuit de sortie qui comprend un ensemble mélangeur 41 - oscilateur local 42 suivi d'un amplificateur 43. L'oscillateur local 39 produit un signal de 9,75 GHz et l'oscillateur 42 un autre signal de 10,6 GHz. Chaque circuit de sortie est relié à l'une des deux entrées d'un commutateur de bande de fréquence 44 dont la sortie est reliée à la borne de sortie 14 de l'agencement qui en revanche est connecté par le câble coaxial 15 au récepteur 3.With reference to FIG. 3, it can be seen that the antenna elements 27 and 28 of each converter device 5, 6 are connected via an amplifier 30 to an input of a bias switch 32 whose output is connected via an amplifier 33 to one of the two inputs of a position switch 35. An amplifier 36 connects the output of the latter to the input of a divider 37 which has a first output circuit comprising a mixer 38 which is associated with a local oscillator 39 and an amplifier 40 and a second output circuit which comprises a mixer assembly 41 - local oscillator 42 followed by an amplifier 43. The local oscillator 39 produces a signal of 9.75 GHz and the oscillator 42 another signal of 10.6 GHz. Each output circuit is connected to one of the two inputs of a frequency band switch 44 whose output is connected to the output terminal 14 of the arrangement which, on the other hand, is connected by the coaxial cable 15 to the receiver 3 .

On décrira ci-après le fonctionnement de l'agencement de convertisseur qui vient d'être décrit. On suppose que le convertisseur 5 est destiné à la réception des signaux du satellite A1 et le convertisseur 6 à la réception des signaux du satellite A2.The operation of the converter arrangement just described will be described below. It is assumed that the converter 5 is intended for reception of the signals of the satellite A1 and the converter 6 for the reception of the signals of the satellite A2.

Tout d'abord on assure que le plan des signaux du satellite A1 ou A2 coïncide avec l'orientation des éléments d'antenne 27, 28 du convertisseur 5 ou 6. L'ajustage se fait par rotation selon l'angle approprié de l'élément guide d'ondes d'entrée 9 de chaque convertisseur. On ajuste également la position angulaire du boîtier support 12 en fonction des élévations différentes des deux antennes, par rotation de l'agencement autour d'un axe parallèle aux parties d'entrée 9.First of all, it is ensured that the plane of the signals of the satellite A1 or A2 coincides with the orientation of the antenna elements 27, 28 of the converter 5 or 6. The adjustment is done by rotation according to the appropriate angle of the input waveguide element 9 of each converter. The angular position of the support housing 12 is also adjusted according to the different elevations of the two antennas, by rotation of the arrangement about an axis parallel to the input portions 9.

Après cette opération de réglage, l'agencement est prêt pour la réception des programmes que transmettent les deux satellites. Dans le récepteur 3, chaque programme est identifié par le satellite A1 ou A2 qui le transmet, par le type de polarisation qui est vertical ou horizontal et par la bande de fréquence basse ou haute que le programme occupe.After this adjustment operation, the arrangement is ready for reception of the programs transmitted by the two satellites. In the receiver 3, each program is identified by the satellite A1 or A2 which transmits it, by the type of polarization which is vertical or horizontal and by the low or high frequency band which the program occupies.

Lorsque l'utilisateur sélectionne un programme, le récepteur 3 commute le commutateur de polarisation 32 du convertisseur approprié sur le type de polarisation des signaux du programme. Cette commutation s'effectue par l'envoi du signal de sélection de polarisation SP approprié, à savoir d'un signal continu de 12 volts si la polarisation est verticale ou d'un signal de 18 volts si la polarisation est horizontale. Puis, après un délai prédéterminé le récepteur sélectionne le satellite A1, A2. Cette sélection se fait par l'envoi ou non envoi d'un certain nombre de salves successives d'oscillations, constituant le signal SA de 22 kHz selon que le programme est émis par l'un ou l'autre satellite. Ensuite, après le délai de temps de sélection du satellite, le récepteur s'accorde sur la bande de fréquence, en envoyant le signal de sélection de bande de fréquence SB au commutateur 43 sous forme d'un signal de modulation de 0 ou 22 kHz. La commande, qui vient d'être décrite, est connue sous les termes des DiSEqC (contrôle numérique des périphériques en réception satellite).When the user selects a program, the receiver 3 switches the bias switch 32 of the appropriate converter to the type of polarization of the program signals. This switching is effected by sending the appropriate polarization selection signal SP, namely a continuous signal of 12 volts if the polarization is vertical or an 18 volts signal if the polarization is horizontal. Then, after a predetermined delay the receiver selects the satellite A1, A2. This selection is made by sending or not sending a number of successive bursts of oscillations, constituting the signal SA of 22 kHz depending on whether the program is broadcast by either satellite. Then, after the satellite selection timeout period, the receiver tunes to the frequency band, sending the frequency band selection signal SB to the switch 43 as a modulation signal of 0 or 22 kHz . The command, which has just been described, is known under the terms of DiSEqC (digital control of satellite reception devices).

A titre d'exemple, l'arrangement du bloc de convertisseur universel selon l'invention, qui vient d'être décrite, est particulièrement approprié pour la réception de satellite éloigné l'un de l'autre de 6 degrés. L'agencement peut être utilisé avec des antennes d'un diamètre de 80 cm et d'un rapport F/D de 0,6. L'agencement de source est monté sur le bras d'antenne pour permettre un ajustage d'élévation relative d'un convertisseur par rapport à l'autre de +/- 4 degrés.For example, the arrangement of the universal converter block according to the invention, which has just been described, is particularly suitable for satellite reception distant from each other by 6 degrees. The arrangement can be used with antennas with a diameter of 80 cm and an F / D ratio of 0.6. The source arrangement is mounted on the antenna arm to allow relative elevation adjustment of one converter relative to the other by +/- 4 degrees.
