A switch comprises a first strip conductor and a second strip conductor, arranged orthogonally in a first plane. Moreover, the switch comprises a first switching conductor, having an orthogonally angled shape relative to the first plane. The switch comprises a switching actuator, which is mechanically connected to the first switching conductor and adapted to move vertically relative to the first plane to a first position and to a second position. The switching actuator is configured, so that in the first position, the first strip conductor is in contact with the first switching conductor and the second strip conductor is in contact with the first switching conductor, and so that in the second position, the first strip conductor and the second strip conductor are not in contact with the first switching conductor.

Switch for switchable attenuator and high frequency switchable attenuator

A switch comprises a first elastic element, an actuator-element mechanically coupled to a first side of the first elastic element, and a first switching conductor, mechanically coupled to a second side of the first elastic element. The switching conductor is configured for moving between a first conductor position and a second conductor position. The actuator-element is configured from moving between a first actuator-element position and a second actuator-element position separated by a predefined actuator-element lift, thereby moving the first side of the first elastic element. The first elastic element moreover is configured for converting a movement of the first side of the first elastic element by the predefined actuator-element lift into the movement of the second side of the first elastic element with a predefined elastic force.

Force-distance controlled mechanical switch

A high frequency switch is provided. The high frequency switch comprises a first high frequency connector, comprising a first inner conductor, integrally formed with a first strip conductor. Moreover, the high frequency switch comprises a second strip conductor arranged orthogonally in a first plane relative to the first strip conductor, a third strip conductor, arranged orthogonally in the first plane relative to the first strip conductor, a first switching conductor, having an orthogonally angled shape relative to the first plane, a second switching conductor, having an orthogonally angled shape relative to the first plane. A switching actuator is mechanically connected to the first switching conductor and to the second switching conductor adapted to move vertically relative to the first plane, to a first position and to a second position.

Switch for switching between different high frequency signals

A measuring bridge () provides a first matching pad (), a second matching pad () and a third matching pad (), wherein all matching pads () comprise at least three resistors () which are arranged in a T-structure. A second resistor () of the second matching pad () is connected to a second resistor () of the first matching pad (), and a third resistor () of the third matching pad () is connected to a third resistor () of the first matching pad (). A second resistor () of the third matching pad () can be connected to a device under test (). A third resistor () of the second matching pad () can be connected to a calibration standard (), and a first resistor () of the second and the third matching pad () are connected in each case to a signal input of an element () which suppresses a common-mode component on its two signal inputs.

Ultra-wide band measurement bridge

A magnetically-tunable filter comprising a filter housing with two tunable resonator spheres made of magnetizable material, which are disposed one above the other in two filter arms. At least one filter arm provides a fin line or slot line disposed on a substrate layer and extending in the direction towards an electrical contact, and a common coupling aperture, thereby connecting the two filter arms to one another. In this context, one resonator sphere is positioned within each filter arm on each of the two sides of the coupling aperture.

Ferrite filter comprising aperture-coupled fin lines

The invention relates to a magnetically tunable filter having a filter housing and having two tunable resonator spheres which comprise magnetizable material and are arranged next to one another in two filter branches. Each filter branch comprises a coplanar line arranged on a substrate layer and extending in the direction of an electrical connection, as well as a common coupling opening so that the two filter branches are connected to one another. A resonator sphere is respectively positioned on each side of the coupling opening inside the two filter branches.
