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.
