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 resonator for a filter is described. The resonator includes a resonator housing, in which a resonator space is formed, a container with a cavity, in which a liquid crystal is contained, the container being at least partially arranged in the resonator space, and a compensating element, which is arranged in the cavity. The compensating element has a coefficient of thermal expansion that is lower than a coefficient of thermal expansion of the liquid crystal.

A resonator, in particular a high-frequency resonator, includes a resonator housing with a resonator space formed therein and a container with a cavity in which a liquid crystal is accommodated, wherein the container is at least partially arranged in the resonator space and includes an electrode configuration for generating an electric control field for controlling the permittivity of the liquid crystal.

Resonator and filter with resonator

A dielectric filter includes a receiving member with a plurality of receiving spaces and a cover. The cover is arranged to cover the receiving spaces in the receiving member. Each receiving space of the plurality of receiving spaces includes a rectangular cavity with a dielectric.
