A switching device for connecting coaxial cables is specified. The switching device includes: a housing with at least two coaxial connectors; a switch rotor arranged in the housing such that it can be rotated about a longitudinal axis; and a first electrical connection, which passes through the switch rotor and in a predetermined position of the switch rotor capacitively couples a first coaxial connector and a second coaxial connector, thus creating an electrical connection between the first coaxial connector and the second coaxial connector.

Rotatable coaxial switching device including electrical connections configured for providing capacitive coupling

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.

Resonator with temperature compensation

A resonator for a channel filter is provided. The resonator includes a cavity; a sidewall which at least partially surrounds and forms the cavity, wherein at least one lateral opening is provided in the sidewall; a first adjusting unit with an adjusting element. A first recess is provided at the adjusting element. The adjusting unit is arranged such that the adjusting element adjoins the lateral opening. The adjusting element is movable relative to the lateral opening such that a resonator frequency of the resonator can be adjusted depending on a position of the adjusting element with reference to the lateral opening.

Channel filter with adjustable frequency

Provided is a channel filter for a communication apparatus. The channel filter includes a first resonator, a coupling element having a first longitudinal section and a second longitudinal section, and a first adjusting element. The coupling element is designed to couple the first resonator at least indirectly with an input or output of the channel filter. The first longitudinal section has a greater width than the second longitudinal section. The first adjusting element is disposed at least partially in the first longitudinal section and at least partially in the second longitudinal section.

Generic channel filter

A microwave filter includes a first adjustable coupling resonator connected via a first coupling iris to an input of the microwave filter, a frequency resonator configured to establish a transmission frequency of the microwave filter and connected to the first adjustable coupling resonator via a second coupling iris, and a second adjustable coupling resonator connected to the frequency resonator via a third coupling iris.

Microwave filter having an adjustable bandwidth

A waveguide busbar for conducting microwaves includes a group input for coupling in a group microwave signal, a plurality of filter inputs for coupling in a plurality of microwave signals, a dual waveguide that comprises a first single waveguide and a second single waveguide. The plurality of filter inputs are disposed along the dual waveguide, as well as at least one adjustable coupling member that provides a connection between the first single waveguide and the second single waveguide and that is configured such that it adjusts a phase length of the connection.

Adjustable waveguide busbar

A waveguide busbar for converting a plurality of high-frequency input signals into high-frequency output signals, includes a waveguide, a plurality of input ports, which are arranged along the waveguide, such that each input port is intended to receive a high-frequency input signal, an output port on the waveguide for delivering the high-frequency output signal and at least one parallel resonator, which is connected to the waveguide busbar between two input ports. The parallel resonator has a mechanically adjustable volume with which a phase relation of the waveguide is adjustable between the two input ports.
