Abstract: A high-frequency conductor system has a high-frequency housing which comprises a housing base, a housing cover which is at a distance from the housing base, and a housing wall which runs circumferentially between the housing base and the housing cover, as a result of which an accommodation space is formed. At least one cable-bound RF bushing is arranged within the accommodation space. The cable-bound RF bushing is electrically isolated from the high-frequency housing. A capacitive coupling element is arranged on at least one part of the circumference of the cable-bound RF bushing and is electrically connected to said cable-bound RF bushing. The capacitive coupling element has two end sides which are oriented transverse or perpendicular to the propagation direction of the cable-bound RF bushing. A first coupling web is electrically connected to the high-frequency housing and is arranged at a distance from the end side in order to generate a capacitive coupling.

Abstract: The invention relates to an improved tunable high frequency filter of coaxial construction, characterized, inter alia, by the following features: The high frequency filter comprises an outer conductor housing (24) having an inner conductor (10) and a housing cover (22); the resonator (1) comprises a tuning element (30) arranged opposite the inner conductor (10), which in the housing cover (22) is held position-adjustably in the axial position of the tuning element (30), at least indirectly, and which extends into the internal space of the resonator; the tuning element (30) comprises a dielectric material, or is formed from a dielectric material such that between the outer thread (32) and the inner thread (41), current transitions are avoided.

Abstract: A temperature-compensated high frequency filter of coaxial construction comprises at least one resonator having an inner conductor and an outer conductor housing. A compensation device made of a second material has a second coefficient of thermal expansion. The compensation device comprises a wall section, which extends in an axial direction and is variable in length in this direction in the event of a temperature change. The wall section is part of the housing wall configured in the manner of an intermediate layer or an upper-most layer located adjacent to the housing cover. The wall section may extend in an axial direction or in a direction transversely thereto and be variable in length in this direction in the event of a temperature change. The wall section is an integral part of the housing cover or is connected to the housing cover, or forms the housing cover having convex outwardly directed curvature.
