Abstract
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
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.
