The printed-circuit board arrangement is used for the electrical connection of an amplifier unit to at least two antenna elements, whereas the at least two antenna elements are embodied on the printed-circuit board arrangement. The antenna elements are coupled via a three-line system to the amplifier unit, where the three-line system comprises three strip lines mounted on the printed-circuit board arrangement extending parallel to one another.

Printed circuit board arrangement for supplying antennas via a three-conductor system for exciting different polarizations

A calibration unit for a measurement device for connecting to a connector embodied in a coaxial manner. The calibration unit provides a housing and an inner conductor, whereas the inner conductor () is embodied centered within an aperture of the housing. The calibration unit provides a connecting element, that the connecting element is inserted into the aperture of the housing and hosts the inner conductor and that the connecting element is embodied in an elastic manner and supports the inner conductor in an elastic manner relative to the housing.

Calibration unit for a measurement device

A printed-circuit board arrangement electrically connects the at least one transmitter and/or receiver unit with at least one antenna element, whereas the at least one transmitter and/or receiver unit and the at least one antenna element are at least partially integrated into the printed-circuit board arrangement. In this context, the printed-circuit board arrangement includes different printed circuit boards, which are mechanically connected to one another in a rigid manner. A first part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a first material which is suitable for high-frequency, and a second part of the printed-circuit board arrangement is formed by at least one printed-circuit board, of which the substrate is made from a second material different from the first material, which is still sufficiently suitable for a low frequency and/or for a direct-voltage range.

Printed-circuit board arrangement for millimeter-wave scanners

The invention relates to a coaxial connecting part which is used to connect a coaxial plug socket to a circuit carrier in an internal conductor. An elastically flexible bellows made of a conductive material is incorporated therein in order to keep axial and radial forces, occurring at the beginning of the socket, away from the substrate.
