  • Patent number: 9437356
    Abstract: The invention concerns a medium frequency transformer with a housing, in which numerous winding chambers, having primary and secondary windings, are disposed, wherein the housing is filled, at least partially, with an insulating liquid. The transformer is distinguished in that numerous winding chambers, filled with the insulating liquid, are disposed in the housing, and at least one winding is disposed in each winding chamber, such that, for the most part, only the windings are surrounded by the insulating medium. Preferably the winding chambers are sealed and separated from one another by means of insulating separating walls, wherein the windings are positioned and fixed in place in the winding chambers, and the winding chambers are filled with the insulating liquid. Between the windings there are thus, according to the invention, at least two insulating barriers, which function simultaneously and consist of solid matter insulation in the form of housing and separating walls, and the insulating liquid.

  • Patent number: 7498552
    Abstract: An electronic microwave circuit with GaAs field-effect transistors, which are integrated onto a semiconductor substrate, for switching high frequency electrical input signals has at least one light source for illuminating the GaAs field-effect transistors. The intensity of the light source and/or the color of the light source are changeable during operation. A calibrating device calibrates the intensity and/or color of the light source using a method according to the invention.

  • Patent number: 7489179
    Abstract: In an electronic high-frequency switch, comprising a field-effect transistor as the switching element, the size of the gate voltage may be switched between at least two values (?5.5 V and ?8 V), according to the desired linearity or switching speed. The switching device for the gate voltage is preferably coupled to a correction device in which different correcting values for the different gate voltage values corresponding to different correcting values for transmission or reflection by the high frequency switch are stored.
