A dielectric element for a resonator and a corresponding resonator are described. The dielectric element has a first chamber and a second chamber, which are fluidically connected to one another by a connecting channel. A liquid crystal is contained in the first chamber, a gas is contained in the second chamber. Changes in the volume of the liquid crystal can be compensated by a change in the volume of the gas, because the liquid crystal can move in the connecting channel. Consequently, such a resonator can be exposed to greatly fluctuating temperature ranges without requiring any further compensation for temperature-induced changes in the volume of the liquid crystal. The dielectric element can also be hermetically closed to complete the production process.

A circuit arrangement having two interconnected high-frequency components, namely a first component and a second component, is described. A connection for transferring high-frequency signals is arranged between the first component and the second component. The connection includes at least one inner conductor, which is at least partially enclosed by an outer conductor. The inner conductor is connected to the first component and to the second component in order to transfer high-frequency signals. The second component includes a contact surface on a connecting surface and the inner conductor is pressed using a pressure force onto the contact surface, to establish a high-frequency connection between the first component and the second component.

A resonator for a filter includes a resonator housing, in which a resonator space is formed. The resonator further includes a dielectric arrangement arranged in the resonator space including a first dielectric element and a second dielectric element, the first dielectric element and the second dielectric element being separated from one another in such a way that a gap is formed between them. Both a first thermal expansion coefficient of the first dielectric element and a second thermal expansion coefficient of the second dielectric element are less than a thermal expansion coefficient of the resonator housing. A temperature-related variation of the resonant frequency of the resonator can therefore be compensated for.
