A strip transmission filter having resonators with impedance skips in which the resonators are provided in a ceramic substrate. The strip transmission filter also includes capacitive couplings. The ceramic substrate has a metallic coating on all sides except for a face side. The coupling structures are at the face side of the substrate. The ceramic substrate is constructed in a stepped formation in a region of the coupling structures and at least one ground terminal. Thus, the adhesion of metallic coating is increased which, in turn, facilitates soldering.
