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.

Abstract: The present invention relates to a method for the manufacture of a high temperature-superconducting layer on a substrate (1a, 1b) comprising the steps of depositing an RBa2Cu3O7-layer (2) with a low growth rate, wherein R represents yttrium, an element of the group of rare-earth elements (atomic number 57 to 71) or mixtures of two or more of these elements, and the deposition of an XBa2Cu3O7-layer (3) onto the RBa2Cu3O7-layer (2) with high growth rate, wherein X represents yttrium, an element of the group of rare-earth elements (atomic number 57-71) or mixtures of two or more of these elements. Preferably, the low growth rate is <1 nm/s and the high growth rate is >1 nm/s, preferably >2 nm/s and the RBa2Cu3O7-layer (2) is preferably deposited onto an at least biaxially textured substrate (1a) or a substrate with an at least biaxially textured buffer layer (1b).
