Isolierfolie, welche einen im Frequenzbereich der Partialresonanzen großen dielektrischen Verlustwinkel besitzt, angebracht. Zur Erhöhung der Spannungsfestigkeit, zur Erzielung eines definierten Streufaktors oder zur Verringerung der Eigenkapazität kann zwischen den Windungslagen zusätzlich eine Isolierfolie 3 eingebracht sein. Je nach dem konstruktiven Aufbau des Übertragers uud der hierdurch bedingten Größe. Anzahl und Frequenz der Partialresonanzen genügt es, die Dämpfungsfolie nur in einem Teil der Windungslagen bzw. der Wicklungen anzubringen. Insulating film, which has a large dielectric loss angle in the frequency range of partial resonances owns, attached. To increase the dielectric strength, to achieve a defined spreading factor or to reduce the self-capacitance An insulating film 3 can also be introduced between the winding layers. Depending on the constructive Structure of the transformer and the resulting size. Number and frequency of the partial resonances it is sufficient to apply the damping film only in part of the winding layers or the windings.
Die Erfindung ist nicht auf den als Ausfuhrungsbeispiel beschriebenen Übertrager mit Lagenwicklung beschränkt. Sie gilt sinngemäß auch für andere Ausführungsformen von Übertragern, z. B. für solche mit Scheibenwicklung.The invention is not limited to the exemplary embodiment described transformer with layer winding limited. It also applies mutatis mutandis to others Embodiments of transformers, e.g. B. for those with disc winding.
Bei einem mit den erfindungsgemäßen Übertragern ausgerüsteten Verstärker, insbesondere gegengekoppelten Verstärker, ist es nicht mehr erforderlich, die Stabilität des Verstärkers durch zusätzliche, die Partialrescranzen ausgleichende Schaltungsmaßnahmen, zu sichern. Der Übertrager ist besonders geeignet für Breitbandverstärker in der Trägerfrequenztechnik.In the case of an amplifier equipped with the transformers according to the invention, in particular with negative feedback Amplifier, it is no longer necessary to increase the stability of the amplifier by additional, the partial rescrances compensating switching measures to secure. The transformer is particularly suitable for Broadband amplifier in carrier frequency technology.

Series resonance brought about by the leakage inductance The use of the partial resonances that occur as a result of the invention, which lies above the damping film described above, brings the special transmission range of the transformer. The advantage is that not only individual partial resonances, these partial resonances can be recorded in multiple ways, but their entire spectrum. The number occur. They are caused by the distributed capacitance based on the fact that the electrical action of the wire windings against each other and their lines of force between the individual windings are too ductile. In this case, only one part can have to pass through the resistor foil at a time. Parts of the winding are involved in the creation of a. This gives the partial resonant circuits a strong resonance point. Such resonance point lossy capacitance and can therefore be counteracted in amplifiers, in particular counteracted. The losses in the amplifiers coupled to the transmission, which are disturbing in appearance, also increase when each winding layer is occupied. With a corresponding impedance curve with a damping film, they increase only so slightly that they lead to self-excitation of the amplifier. they do not appear disturbing.
In the case of high-quality amplifiers, for example for In addition to the damping film, for example, to increase carrier frequencies, at which one has to make use of negative feedback of the dielectric strength, to reduce the circuitry, there is inherent capacitance or to achieve a certain known, disturbing partial resonances, which represent a Par scattering factor in addition an insulating film used represent an allele resonance circuit, through a series re-.
