Abstract: A coupling conductor for a YIG filter or YIG oscillator, which may be produced from a metallic foil by eroding, laser cutting and/or etching of a metallic foil. The coupling conductor includes at least one curved section, which at least partially surrounds a YIG element and at least one conductor section.

Abstract: The invention relates to a magnetically tunable filter having a filter housing and having two tunable resonator spheres which comprise magnetizable material and are arranged next to one another in two filter branches. Each filter branch comprises a coplanar line arranged on a substrate layer and extending in the direction of an electrical connection, as well as a common coupling opening so that the two filter branches are connected to one another. A resonator sphere is respectively positioned on each side of the coupling opening inside the two filter branches.

Abstract: A base element for a YIG band-pass filter or a YIG oscillator is formed from a non-magnetic material and comprises filter chambers, which are formed in the base element, wherein the filter chambers are connected to one another by channels, and YIG elements are disposed in the filter chambers and electromagnetically coupled by coupling loops disposed in the filter chambers. Slots into which contact lugs connected to the coupling loops extend, are formed in the base element. Recesses intersect the slots and and are used to accommodate a solder mass. The contact lugs are fixed in the recesses by the solder mass.
