Description

Grundkörper für einen YIG-Filter oder YIG-Oszillator Basic body for a YIG filter or YIG oscillator
Die Erfindung betrifft einen Grundkörper für ein YIG- Bandpaßfilter oder einen YIG-Oszillator gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a base body for a YIG bandpass filter or a YIG oscillator according to the preamble of claim 1.
YIG-Bandpaßfilter oder YIG-Oszillatoren verfügen über zumindest ein YIG-Element, welches vorzugsweise kugelförmig ausgebildet und aus einem Yttrium-Eisen-GranatYIG bandpass filters or YIG oscillators have at least one YIG element, which is preferably spherical and made of an yttrium iron garnet
(Yttrium-Iron-Garnet YIG) hergestellt ist. Die(Yttrium Iron Garnet YIG) is made. The
Resonatorwirkung wird mittels Koppelschleifen vermittelt, die so ausgebildet und angeordnet sein müssen, daß der Mittelpunkt des YIG-Elements und der Mittelpunkt des Biegeradius einer Koppelschleife genau übereinstimmen.Resonator effect is mediated by coupling loops, which must be designed and arranged so that the center of the YIG element and the center of the bending radius of a coupling loop match exactly.
Ein YIG-Bandpaßfilter mit entsprechend ausgebildeten Koppelschleifen ist beispielsweise aus der US 4,480,238 bekannt. Der durchstimmbare YIG-Bandpaßfilter weist dabei einen Grundkörper auf, welcher Schlitze zur Aufnahme von isolierten Plättchen umfaßt, die an einer Kante eine leitfähige Beschichtung aufweisen, die als Kopplungsleitung dient. Weiterhin sind Filterkammern zurA YIG bandpass filter with correspondingly formed coupling loops is known, for example, from US Pat. No. 4,480,238. The tunable YIG bandpass filter in this case has a base body, which comprises slots for receiving insulated plates, which have at one edge a conductive coating, which serves as a coupling line. Furthermore, filter chambers for
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 festenRecording of the YIG elements provided. 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 platelets are solid
Positionen fixiert.Fixed positions.
Nachteilig an den aus der Praxis bekannten YIG- Bandpaßfiltern mit Drahtschleifen als Koppelelementen ist insbesondere, daß die Herstellung der YIG-Filter durch das händische Biegen der Koppelschleifen aufwendig, kompliziert und mit einer hohen Ausschußquote verbunden ist. Aufgabe der vorliegenden Erfindung ist es demnach, einen Grundkörper für ein YIG-Filter oder einen YIG-Oszillator zu schaffen, der die Verwendung von vorgefertigten Koppelschleifen bei reproduzierbar hoher Montagepräzision ermöglicht.A disadvantage of the known from practice YIG bandpass filters with wire loops as coupling elements is in particular that the production of the YIG filter by the manual bending of the coupling loops consuming, complicated and is associated with a high rejection rate. Object of the present invention is therefore to provide a base for a YIG filter or a YIG oscillator, which allows the use of prefabricated coupling loops with reproducible high mounting precision.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is solved by the characterizing features of claim 1.

Im Folgenden werden anhand der Zeichnung bevorzugte Ausführungsbeispiele der Erfindung beispielhaft dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen:In the following, preferred embodiments of the invention are shown by way of example with reference to the drawing and explained in more detail in the following description. Show it:

Die Fig. 1 und 2 zeigen in einer Schematischen, perspektivischen Ansicht bzw. einer schematischen Aufsicht ein Ausführungsbeispiel eines YIG-Bandpaßfilters 1, der einen Grundkörper 2 und im Ausführungsbeispiel vier in dem Grundkörper 2 ausgebildete Filterkammern 3 mit ebenso vielen YIG-Elementen 4 aufweist. Die YIG-Elemente 4 sind dabei kugelförmig aus einem Yttrium-Eisen-Granat ausgebildet und durch Koppelschleifen 5 elektromagnetisch gekoppelt.1 and 2 show in a schematic, perspective view and a schematic plan view of an embodiment of a YIG bandpass filter 1, which has a base body 2 and in the embodiment four formed in the base body 2 filter chambers 3 with as many YIG elements 4. The YIG elements 4 are spherically formed from an yttrium-iron garnet and electromagnetically coupled by coupling loops 5.
Die Filterkammern 3 sind durch Kanäle 6 miteinander verbunden, in welche die Koppelschleifen 5 eingelegt werden. Die Kanäle besitzen dabei genügend Abstand zu den jeweiligen Koppelschleifen, um mit diesen Leitungssysteme zu bilden. Die Anzahl der Filterkammern 3 ist dabei nicht auf vier beschränkt, sondern kann auch weniger oder mehr betragen.The filter chambers 3 are interconnected by channels 6, in which the coupling loops 5 are inserted. The channels have enough distance to the respective coupling loops to form with these line systems. The number of filter chambers 3 is not limited to four, but may be less or more.
Wie insbesondere aus Fig. 1 hervorgeht, verlaufen die Kanäle 6 dabei nicht in voller Länge durch die gesamte axiale Erstreckung des Grundkörpers 2. Zwischen denAs can be seen in particular from FIG. 1, the channels 6 do not run in full length through the entire axial extension of the basic body 2
Filterkammern 3 sind die Kanäle 6 nur bis zu einer bestimmten Tiefe, die etwas mehr als die Einlegetiefe derFilter chambers 3, the channels 6 only to a certain depth, which is slightly more than the insertion depth of
Kopplungsleitungen 5 beträgt, ausgebildet. Die Fig. 3A und 3B verdeutlichen dies durch zwei Darstellungen desCoupling lines 5 is formed. FIGS. 3A and 3B illustrate this by two illustrations of FIG
Grundkörpers 2 in entgegengesetzten Blickrichtungen. InBasic body 2 in opposite directions. In
Fig. 3A ist die Unterseite 7 des Grundkörpers 2 dargestellt, während Fig. 3B die Oberseite 8 zeigt. InFIG. 3A shows the underside 7 of the basic body 2, while FIG. 3B shows the upper side 8. In
Fig. 3A sind entsprechend die Kanäle 6 zwischen den Filterkammern 3 nicht sichtbar, da sie sich nicht durch die gesamte axiale Dicke des Grundkörpers 2 erstrecken, während sie in Fig. 3B an der Oberfläche 8 sichtbar sind.According to FIG. 3A, the channels 6 between the filter chambers 3 are not visible, since they do not extend through the entire axial thickness of the main body 2, while they are visible on the surface 8 in FIG. 3B.
Demgegenüber sind jenseits der Filterkammern 3 sich mit blinden Enden radial nach außen erstreckende Schlitze 11 über die gesamte axiale Dicke des Grundkörpers ausgebildet. Ebenfalls existiert ein Schlitz 12 zwischen den Resonatoren am Ein- und Ausgang des Filters.On the other hand, beyond the filter chambers 3, slots 11 extending radially outwards with blind ends are formed over the entire axial thickness of the main body. There is also a slot 12 between the resonators at the input and output of the filter.
Ebenfalls radial außerhalb der Filterkammern 3 sowie die Schlitze 11 und 13 schneidend sind Ausnehmungen 9 ausgebildet, welche sich im Gegensatz zu den zwischen den Filterkammern 3 verlaufenden Kanälen 6 durch die gesamte axiale Dicke des Grundkörpers 2 erstrecken. Die Ausnehmungen 9 erfüllen dabei die Aufgabe, einerseits die Koppelschleifen 5 aufzunehmen und gleichzeitig die Zufuhr von Lotmasse bei der Montage der Koppelschleifen 5 zu ermöglichen.Also radially outside the filter chambers 3 and the slots 11 and 13 intersecting recesses 9 are formed, which extend in contrast to the extending between the filter chambers 3 channels 6 through the entire axial thickness of the base body 2. The Recesses 9 thereby fulfill the task, on the one hand to receive the coupling loops 5 and at the same time to allow the supply of solder mass during the assembly of the coupling loops 5.
Um die einfache Montage der Koppelschleifen 5 zu ermöglichen, werden diese zunächst mittels eines geeigneten Verfahrens wie Ätzen, Laserschneiden oder Erodieren aus einer Folie in gleichbleibender Genauigkeit und Reproduzierbarkeit hergestellt. Die Koppelschleifen 5 weisen dabei zur Erleichterung der Montage Kontaktfahnen 10 auf, die vorzugsweise einstückig mit den Koppelschleifen 5 ausgebildet und vorzugsweise rechteckig geformt sind, wobei eine Kantenlänge der Kontaktfahnen 10 ungefähr der axialen Dicke des Grundkörpers 2 entspricht.In order to enable the simple assembly of the coupling loops 5, they are first produced by means of a suitable method such as etching, laser cutting or eroding from a film with constant accuracy and reproducibility. The coupling loops 5 have to facilitate assembly to contact lugs 10, which are preferably formed integrally with the coupling loops 5 and preferably rectangular in shape, wherein an edge length of the contact lugs 10 corresponds approximately to the axial thickness of the base body 2.
Dies erleichtert die Montage der Koppelschleifen 5, da diese nach dem Einlegen in die Schlitze 11 und 13 so weit in die Schlitze 11 und 13 hineinrutschen, bis die Kontaktfahnen 10 auf dem Montageuntergrund aufliegen, auf welchem der Grundkörper 2 während des Montagevorgangs liegt. Die Kontaktfahnen 10 schließen dann mit der Unterseite 7 und der Oberseite 8 des Grundkörpers 2 bündig ab. Auf diese Weise kann sichergestellt werden, daß die Koppelschleifen 5 stets in gleicher Position hochgenau montiert werden können und der gewünschte elektromagnetische Kopplungsgrad erreicht werden kann.This facilitates the assembly of the coupling loops 5, as they slip into the slots 11 and 13 so far after insertion into the slots 11 and 13 until the contact lugs 10 rest on the mounting surface on which the base body 2 is located during the assembly process. The contact lugs 10 then close flush with the bottom 7 and the top 8 of the base body 2. In this way it can be ensured that the coupling loops 5 can always be mounted in the same position with high precision and the desired degree of electromagnetic coupling can be achieved.
Die in die Ausnehmungen 9 eingebrachte Lotmasse schließt die Kontaktfahnen 10 so ein, daß einerseits eine zuverlässige Fixierung der Koppelschleifen 5 in den Ausnehmungen 9 und andererseits eine leitende Verbindung zwischen dem Grundkörper 2 und den Koppelschleifen 5 erfolgt. Die Lotmasse fließt dabei ebenfalls bis auf die Montageunterlage und schließt somit ebenfalls unten und oben bündig mit der Oberseite 8 und der Unterseite 7 des Grundkörpers 2 ab, so daß nach der Montage ein glattes Bauteil vorliegt, welches ohne Gefahr von Verhaken oder Verlieren der Koppelschleifen 5 weiterbearbeitet werden kann.The introduced into the recesses 9 solder mass includes the contact lugs 10 so that on the one hand, a reliable fixation of the coupling loops 5 in the recesses 9 and on the other hand a conductive connection between the base body 2 and the coupling loops 5 takes place. The solder mass also flows down to the mounting pad and thus also includes the bottom and top flush with the top 8 and the bottom 7 of the body 2, so that after assembly is a smooth component, which without risk of snagging or Loss of the coupling loops 5 can be further processed.
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel begrenzt und für beliebig ausgestaltete YIG-Filter 2 oder YIG-Oszillatoren geeignet. Die einzelnen Merkmale sind dabei beliebig miteinander kombinierbar. The invention is not limited to the illustrated embodiment and suitable for any configured YIG filter 2 or YIG oscillators. The individual features can be combined with each other as desired.
