Abstract: A coaxial RF connector with inner and outer conductors has an outer conductor with a plurality of longitudinal slits forming a plurality of spring loaded contact elements. A contact sleeve is arranged movable in axial direction surrounding coaxially the outer conductor. The contact sleeve has a radial contact face which is in contact with the spring loaded contact elements and an axial contact face which has a plane orthogonal to the center axis of the connector for contacting a counter connector.

Abstract: A coaxial RF connector system comprises RF connectors with inner and outer conductors providing a galvanic contact. An outer conductor of a first connector has a plurality of longitudinal slits forming a plurality of spring-loaded contact elements which contact a solid outer conductor of a second connector. The first connector has a centering sleeve which is one monolithic part with the outer conductor for centering the solid outer conductor of the second connector. An insulation sleeve is provided between the centering sleeve and the solid outer conductor. This prevents a galvanic contact and improves PIM.

Abstract: The invention relates to a rotary joint which comprises two components mounted for rotation relative to one another about an axis of rotation, and each comprising electrically conductive material and jointly enclosing at least one intermediate gap, which is in the form of a capacitive gap for the purpose of transmitting electrical signals and/or energy. The two components are mounted by means of at least one plain bearing such that they are axially fixed longitudinally relative to the axis of rotation and can be rotated relative to one another about the axis of rotation. The plain bearing has at least one plain bearing gap, at least some regions of which correspond to the capacitive gap. The invention is characterized in that the surface of at least one of the two components has, at least in the region of the capacitive gap, the electrically conductive material with an electrically insulating layer in the form of a metal oxide layer.

Abstract: A quad-mode microwave or RF bandpass filter comprises a housing of a conductive material defining a cylindrical cavity and containing a cylindrical dielectric resonator defined by a parallel pair of face surfaces. The dielectric resonator is held within the housing between a pair of support plates of a dielectric material. Internal coupling elements are provided above and/or below the dielectric resonator for coupling between resonating modes. Further mode coupling elements are protruding into the housing.

Abstract: The invention is a coaxial conductor structure for fault-free transmission of a TEM Mode of a HF signal wave within at least one band of frequency bands forming in the context of a dispersion relation. An inner conductor and an outer conductor are spaced radially apart from the inner conductor and an axially extending common conductor section of the inner and the outer conductor. A number n of electrically conductive ring-shaped structures are each fitted between the inner and outer conductor to be radially spaced apart, each of which have an electrical path completely surrounding the inner conductor and are arranged with a spatially periodic sequence with an equal distance between the two ring-shaped structures which are adjacent along the conductor section.
