57 Zusammenfassung AB [EN] The invention relates to a device for high-frequency and/or radio-frequency tuning. <??>An object of the invention is to provide a new and improved approach for enabling an increased high-frequency and/or radio-frequency tuning range by a reduced complexity and board space even with regard to multiband and/or multistandard purposes, in particular suitable within the radio design for mobile communication systems and/or networks, preferably by simultaneously reducing the undesirable parasitic influences. The invention proposes a device for high-frequency and/or radio-frequency tuning comprising within one IC-package a first variable capacitor (C1) and at least one second capacitor (C2), each of the at least one second capacitor (C2) being fixed or variable respectively, at least one signal path connected to the first variable capacitor (C1) and providing at least one input and one output port (rf-port1, rf-port2) and at least one controllable switching means (SC2) for individually connecting and disconnecting at least one of the at least one second capacitor (C2) into the signal path or from the signal path, in particular in parallel to the first variable capacitor (C1).
