A test coupler for supplying a device under test with test signals contains a first coaxial connector, a waveguide port, and a first strip conductor. Test signals of a lower frequency range are supplied to the first coaxial connector. Test signals of an upper frequency range are supplied to the waveguide port. The test coupler guides the test signals on the first strip conductor to the device under test.

Measuring coupler using strip conductor technology

A coupler comprises a first line and a second line in each case with two connectors. The lines run in spatial proximity and are coupled. A first connector of the first line and a first connector of the second line are disposed in spatial proximity. A second connector of the first line and a second connector of the second line are disposed in spatial proximity. A signal does not couple or couples only with a high attenuation from the first connector of the first line to the first connector of the second line. The signal is split, in particular, at the design frequency, into largely identical parts to the second connector of the first line and the second connector of the second line. The first line and the second line in this context are strip conductors.

Forward coupler with strip conductors

Electrical switching device, especially a high-frequency switching device, with at least one oblong electrical switching element, which is arranged with one contact end between two fixed-contact elements spaced a transverse distance from one another and can be moved by two adjustment elements forming a transverse movement drive transversely to a longitudinal direction optionally towards the one or the other fixed-contact element. The adjustment elements are disposed laterally alongside the switching element and can be moved transversely to and from the switching element. In order to improve the transverse movement drive for the switching element, the switching element-comprises magnetic material, wherein the adjustment elements are formed by magnets.

Electrical switching device comprising magnetic displacement elements for a switching element

In a directional coupler with two coupled lines arranged in a flat chamber of an enclosed metal housing within the coupling region side-by-side in the longitudinal direction and at a spacing distance from one another, of which the ends are connected to connecting ports attached at the sides of the metal housing, these coupled lines include flat, sheet-metal strip conductors, which are arranged within the coupling region with their broad sides facing towards one another side-by-side at a spacing distance and held by several support elements made of insulating material in a cantilever manner at a spacing distance from the opposing internal walls of the flat metal-housing chamber within the latter. In this context, at least one strip conductor is curved relative to the opposing strip conductor in such a manner that the spacing distance of the strip conductors in coupling region increases starting from the beginning of the coupling region approximately exponentially up to the end of the coupling region. The width of the two strip conductors increases within the coupling region.

Directional coupler

An electrical switching device, especially a high-frequency switching device, comprising an elongate electrical switching element, a contact end of which is disposed between two opposite contact elements that are transversally spaced apart from each other. The switching element can be selectively moved perpendicularly to the longitudinal direction thereof towards one or the other opposite contact element by two adjusting elements that are located on both sides next to the switching element. In order to eliminate or at least reduce frictional processes and the risk of the electrical contact being damaged by abrasion, the switching element is made at least in part of magnetic material while the adjusting elements are formed by two magnet assemblies, the magnetic force of one magnet assembly or the other magnet assembly being selectively reducible or increasable.
