Description

Die Erfindung betrifft ein YIG-Filter oder ein YIG-Oszillator.The invention relates to a YIG filter or a YIG oscillator.

YIG-Bandpaßfilter oder YIG-Oszillatoren verfügen über zumindest einen Resonator, welcher vorzugsweise kugelförmig ausgebildet und aus einem Yttrium-Eisen-Granat (Yttrium-Iron-Garnet YIG) hergestellt ist. Die Resonatorwirkung wird mittels Kopplungsleitungen vermittelt, die so ausgebildet und angeordnet sein müssen, daß der Mittelpunkt des Resonators und der Mittelpunkt des Biegeradius einer Kopplungsleitung genau übereinstimmen.YIG band-pass filter or YIG oscillators have at least one resonator, which is preferably spherical and made of a yttrium iron garnet (Y ttrium- I RON G arnet YIG) is prepared. The Resonatorwirkung is mediated by coupling lines, which must be designed and arranged so that the center of the resonator and the center of the bending radius of a coupling line match exactly.

Ein YIG-Bandpaßfilter mit entsprechend ausgebildeten Kopplungsleitungen ist beispielsweise aus der Druckschrift US 4,480,238 bekannt. Der durchstimmbare YIG-Bandpaßfilter weist dabei einen Grundkörper auf, welcher Schlitze zur Aufnahme von isolierten Plättchen, die an einer Kante eine leitfähige Beschichtung aufweisen, die als Kopplungsleitungen dient, umfaßt. Weiterhin sind Filterkammern zur Aufnahme der YIG-Elemente vorgesehen. Die Plättchen werden so über die YIG-Elemente in die Schlitze eingelegt, daß die YIG-Elemente in Einbuchtungen in den mit der leitfähigen Beschichtung versehenen Kanten angeordnet sind. Die YIG-Elemente und die Plättchen werden in festen Positionen fixiert.A YIG bandpass filter with correspondingly formed coupling lines is for example from the document US 4,480,238 known. The tunable YIG bandpass filter in this case has a base body, which slots for receiving isolated platelets having at one edge a conductive coating which serves as coupling lines comprises. Furthermore, filter chambers are provided for receiving the YIG elements. The platelets are placed over the YIG elements in the slots so that the YIG elements are arranged in indentations in the edges provided with the conductive coating. The YIG elements and the plates are fixed in fixed positions.

Nachteilig an dem aus der oben genannten Druckschrift bekannten YIG-Bandpaßfilter ist insbesondere die aufwendige Herstellung der die Kopplungsleitungen bildenden Plättchen. Der als Träger dienende Isolator muß zunächst entsprechend geformt und dann mit der leitfähigen Beschichtung versehen werden. Dies ist aufwendig und ausschußgefährdet, da die Beschichtung durch die geringe Schichtdicke empfindlich gegen Beschädigungen ist.A disadvantage of the YIG bandpass filter known from the above-mentioned publication is, in particular, the complicated manufacture of the platelets forming the coupling lines. The serving as a carrier insulator must first be appropriately shaped and then provided with the conductive coating. This is expensive and prone to jeopardy because the coating is sensitive to damage due to the small layer thickness.

Aufgabe der vorliegenden Erfindung ist es, ein YIG-Filter oder YIG-Oszillator zu schaffen, mit Kopplungsleitungen die einfach herstellbar, unempfindlich gegen Beschädigungen und leicht einbaubar sind.Object of the present invention is to provide a YIG filter or YIG oscillator, with coupling lines that are easy to manufacture, insensitive to damage and easy to install.

Die Aufgabe wird bezüglich der Kopplungsleitungen durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved with respect to the coupling lines by the characterizing features of claim 1.

Fig. 1A zeigt in einer schematischen, perspektivischen Ansicht ein Ausführungsbeispiel eines YIG-Bandpaßfilters 2, der einen Grundkörper 3 und im Ausführungsbeispiel vier in dem Grundkörper 3 ausgebildete Filterkammern 4 mit ebenso vielen YIG-Elementen 6 aufweist. Fig. 1A shows in a schematic, perspective view of an embodiment of a YIG bandpass filter 2, which has a base body 3 and in the embodiment, four formed in the base body 3 filter chambers 4 with as many YIG elements 6.

Die YIG-Elemente 6 sind dabei kugelförmig aus einem Yttrium-Eisen-Granat ausgebildet, auf Haltern 10 beispielsweise durch Kleben mit Epoxydharz montiert und durch Kopplungsleitungen 1 elektromagnetisch gekoppelt.The YIG elements 6 are spherically formed from an yttrium-iron garnet, mounted on holders 10, for example by gluing with epoxy resin and electromagnetically coupled by coupling lines 1.

Die Filterkammern 4 sind durch Schlitze 5 miteinander verbunden, in welche die Kopplungsleitungen 1 eingelegt sind. Dabei sind im Ausführungsbeispiel jeweils zwei der Filterkammern 4 gleich ausgebildet. In die mit 4a bezeichneten Filterkammern 4 münden Koaxialkabel 11 ein, über die der Signalein- bzw. -auslauf erfolgt. Die mit 4b bezeichneten Filterkammern 4 weisen dagegen nur die YIG-Elemente 6 auf. Die Anzahl der Filterkammern 4b ist dabei nicht auf zwei beschränkt, sondern kann auch eins oder mehr betragen so daß die Gesamtzahl der Filterkammern 4 drei oder mehr betragen kann.The filter chambers 4 are interconnected by slots 5, in which the coupling lines 1 are inserted. In this case, two of the filter chambers 4 are identical in the embodiment. In the designated filter chambers 4 4a 4 open coaxial cable 11, via which the signal input and output takes place. By contrast, the filter chambers 4 denoted by 4b have only the YIG elements 6. The number of filter chambers 4b is not limited to two, but may be one or more so that the total number of filter chambers 4 may be three or more.

Fig. 1B zeigt zur besseren Verständlichkeit die Anordnung der Kopplungsleitungen 1 sowie der auf ihren Haltern 10 montierten YIG-Elemente 6 ohne den umgebenden Grundkörper 3. Fig. 1B shows for ease of understanding the arrangement of the coupling lines 1 and mounted on their holders 10 YIG elements 6 without the surrounding body. 3

Die Kopplungsleitungen 1 sind im Ausführungsbeispiel in zwei verschiedenen Formen ausgeführt. Die die Filterkammern 4b untereinander verbindende Kopplungsleitung 1 ist als Ein- bzw. Ausgangsleitung 1a ausgeführt, während die im Ausführungsbeispiel drei weiteren Kopplungsleitungen 1 als Verbindungsleitungen 1b ausgeführt sind.The coupling lines 1 are executed in the embodiment in two different forms. The filter chambers 4b interconnecting coupling line 1 is designed as input or output line 1a, while in the embodiment, three further coupling lines 1 are designed as connecting lines 1b.

Wie aus Fig. 1B hervorgeht, weisen die Kopplungsleitungen 1 Kontaktfahnen 8 auf, welche einerseits der Masseverbindung der Kopplungsleitungen 1 im Grundkörper 3 und andererseits der Fixierung der Kopplungsleitungen 1 in den Schlitzen 5 dienen. Die Kontaktfahnen 8 sind dabei rechteckig geformt, wobei eine Kantenlänge der Kontaktfahnen 8 ungefähr der axialen Dicke des Grundkörpers 2 entspricht.How out Fig. 1B shows, the coupling lines 1 on tabs 8, which serve on the one hand, the ground connection of the coupling lines 1 in the base body 3 and on the other hand, the fixation of the coupling lines 1 in the slots 5. The contact lugs 8 are rectangular in shape, wherein an edge length of the contact lugs 8 corresponds approximately to the axial thickness of the base body 2.

Betrachtet man die Fig. 2A und 2B, ist erkennbar, wodurch sich die Kopplungsleitungen 1 gemäß Fig. 2B von herkömmlichen Kopplungsleitungen 1 gemäß Fig. 2A unterscheiden.Looking at the FIGS. 2A and 2B , is recognizable, whereby the coupling lines 1 according to Fig. 2B from conventional coupling lines 1 according to FIG Fig. 2A differ.

Den beiden Ausführungsformen ist gemeinsam, daß jeweils zumindest ein gekrümmter Abschnitt 17 vorgesehen ist, der jeweils ein YIG-Element 6 so zumindest teilweise umgreift, daß ein Mittelpunkt des YIG-Elements 6 mit einem Mittelpunkt des gekrümmten Abschnitts 17 zusammenfällt. Weiterhin ist zumindest ein Leitungsabschnitt 18 vorgesehen.The two embodiments have in common that in each case at least one curved portion 17 is provided, which surrounds a respective YIG element 6 so at least partially, that a center of the YIG element 6 coincides with a center of the curved portion 17. Furthermore, at least one line section 18 is provided.

Die in Fig. 2A dargestellte Kopplungsleitung 1 gemäß dem Stand der Technik ist aus einem Draht gebogen. Hierbei werden zunächst die YIG-Elemente 6 in den in Fig. 2A und 2B nicht näher dargestellten Grundkörper 3 eingebracht und dann der nur grob vorgebogene Draht in die Schlitze 5 eingelegt. Eine Messung des Koppelungsgrades ergibt dann, wo die Kopplungsleitung 1 noch nachgebogen werden muß. Dies erfolgt händisch mittels eines geeigneten Werkzeugs. Danach muß erneut kontrolliert und u.U. wieder nachjustiert werden. Zu diesem Zweck muß jedes Mal der YIG-Filter 2 oder YIG-Oszillator geöffnet und anschließend zum Vornehmen der Messung wieder zusammengebaut werden. Das Verfahren ist somit äußerst aufwendig und führt oftmals sogar dazu, daß das Werkstück nach mehreren Iterationen vollkommen verworfen werden muß, weil keine befriedigende Kopplung erreicht wird.In the Fig. 2A shown coupling line 1 according to the prior art is bent from a wire. in this connection First, the YIG elements 6 in the in FIGS. 2A and 2B introduced basic body 3, not shown, and then inserted only roughly pre-bent wire in the slots 5. A measurement of the degree of coupling results where the coupling line 1 still needs to be bent. This is done manually by means of a suitable tool. Thereafter must be checked again and readjusted. For this purpose, each time the YIG filter 2 or YIG oscillator must be opened and then reassembled to make the measurement. The method is thus extremely complicated and often even leads to the fact that the workpiece must be completely discarded after several iterations, because no satisfactory coupling is achieved.

Demgegenüber werden die erfindungsgemäß ausgestalteten Kopplungsleitungen 1 gemäß Fig. 2B aus einer metallischen Folie durch geeignete Verfahren wie Ätzen, Erodieren, Schneiden, insbesondere Laserschneiden oder Wasserstrahlschneiden und/oder Stanzen hergestellt und montiert. Danach erfolgt die korrekte Positionierung der YIG-Elemente 6 relativ zu den Kopplungsleitungen 1.In contrast, the inventively designed coupling lines 1 according to Fig. 2B made of a metallic foil by suitable methods such as etching, eroding, cutting, in particular laser cutting or water jet cutting and / or punching and assembled. Thereafter, the correct positioning of the YIG elements 6 takes place relative to the coupling lines. 1

Die Folie besteht aus einer Kupfer-Beryllium-Legierung, um sowohl den Anforderungen an die Elastizität als auch an die Festigkeit zu genügen. Die Dicke der Folie beträgt dabei vorzugsweise ca. 50 µm.The film is made of a copper-beryllium alloy to meet both the requirements of elasticity and strength. The thickness of the film is preferably about 50 microns.

Die Herstellung der Kopplungsleitungen 1 aus der Folie erfolgt in mehreren Bearbeitungsschritten. Zunächst wird die Folie gereinigt und auf beiden Seiten mit einem Positivlack bei einer Justiergenauigkeit von ca. 5 µm in einer Schichtdicke von ca. 5 µm aufgetragen, um eine Maske zu erstellen. Danach erfolgt die Herstellung der Kopplungsleitungen 1 beispielsweise durch Sprühätzen mit Eisenchlorid. (FeCl3) Anschließend werden die in Form eines Trägers 9 mit einer vorher festgelegten Anzahl von Kopplungsleitungen 1 von Lackresten befreit und galvanisch mit einer Goldbeschichtung von ca. 5 µm versehen. Danach folgt ein Härtungsvorgang für beispielsweise eine Stunde bei 325°C. Dann können die Kopplungsleitungen aus dem Folien-Träger 9 gelöst und verbaut werden.The preparation of the coupling lines 1 from the film takes place in several processing steps. First, the film is cleaned and applied on both sides with a positive resist at an alignment accuracy of about 5 microns in a layer thickness of about 5 microns to create a mask. Thereafter, the preparation of the coupling lines 1, for example, by spray etching with iron chloride. (FeCl 3) Subsequently, the liberated in the form of a carrier 9 with a predetermined number of coupling lines 1 of all paint residues and galvanically provided with a gold coating of about 5 microns. After that follows a curing process for example, one hour at 325 ° C. Then the coupling lines can be released from the film carrier 9 and installed.

Die Kopplungsleitungen 1 weisen durch das beschriebene Herstellungsverfahren eine feste Form mit einem genau definierten Krümmungsradius in den gekrümmten Abschnitten 17 bei einer gleichmäßigen Krümmung auf. Die YIG-Elemente 6 werden dann relativ zu den Kopplungsleitungen 1 ausgerichtet. Dies ist gegenüber dem Stand der Technik einfacher und mit erheblich geringerem Aufwand verbunden, weil die Herstellungsgenauigkeit bei den erfindungsgemäß ausgestalteten Kopplungsleitungen 1 erheblich größer ist als bei händisch gebogenen Kopplungsleitungen 1.The coupling lines 1 have by the manufacturing method described a solid shape with a well-defined radius of curvature in the curved portions 17 at a uniform curvature. The YIG elements 6 are then aligned relative to the coupling lines 1. This is compared to the prior art simpler and associated with considerably less effort, because the manufacturing accuracy of the present invention designed coupling lines 1 is considerably larger than in manually curved coupling lines. 1

Fig. 3A zeigt in einer schematischen Darstellung einen Träger 9, welcher die für einen YIG-Bandpaßfilter 2 mit vier YIG-Elementen 6 benötigten Kopplungsleitungen 1 enthält. Fig. 3A shows a schematic representation of a carrier 9, which contains the coupling lines 1 required for a YIG bandpass filter 2 with four YIG elements 6.

Wie bereits weiter oben erwähnt, sind die Kopplungsleitungen 1 im Ausführungsbeispiel in Form einer Ein- bzw. Ausgangsleitung 1a sowie dreier Verbindungsleitungen 1b ausgebildet. Die erstere ist in Fig. 3A ganz unten in dem Folien-Träger 9 angeordnet, die letzteren darüber.As already mentioned above, the coupling lines 1 are formed in the embodiment in the form of an input or output line 1a and three connecting lines 1b. The former is in Fig. 3A arranged at the bottom of the film carrier 9, the latter above.

Die Fig. 3B und 3C zeigen die in Fig. 3A mit IIIB und IIIC bezeichneten Ausschnitte aus dem Träger 9. In Fig. 3B ist eine der drei Verbindungsleitungen 1b dargestellt, während Fig. 3C die Ein- bzw. Ausgangsleitung 1a zeigt.The Figs. 3B and 3C show the in Fig. 3A sections of support 9 labeled IIIB and IIIC Fig. 3B one of the three connecting lines 1b is shown while Fig. 3C the input or output line 1a shows.

Aus den Fig. 3B und 3C ist erkennbar, daß die Kopplungsleitungen 1 nach dem Vorgang des Ätzens, Schneidens, Stanzens oder Erodierens aus der Folie vor dem Vereinzeln in dem Träger 9 durch Stege 12 gehalten werden, die an den Kontaktfahnen 8 ausgebildet sind. Beim Vereinzeln der Kopplungsleitungen 1 werden die Kopplungsleitungen 1 aus dem Träger 9 durch Brechen der Stege 12 separiert. Nach dem Vereinzeln werden die Kopplungsleitungen 1 entsprechend ihrer Form in dem Grundkörper 3 montiert und durch Löten, Schweißen oder ein anderes, die elektrische Leitfähigkeit erhaltendes Verbindungsverfahren in dem Grundkörper 3 fixiert.From the Figs. 3B and 3C It can be seen that the coupling lines 1 are held by the process of etching, cutting, punching or eroding from the film prior to separation in the carrier 9 by webs 12 which are formed on the contact lugs 8. When separating the coupling lines 1, the coupling lines 1 from the carrier 9 by breaking the Webs 12 separated. After singulation, the coupling lines 1 are mounted in the base body 3 according to their shape and fixed in the base body 3 by soldering, welding or another method of maintaining the electrical conductivity.
