Abstract: A coaxial HF plug-in connector comprises an axial bore embodied in an external conductor material on a connection side, in which an electric component is arranged. The aim is to improve the connector. For this purpose, the component in the axial bore is embodied in the form of an output branch which comprises a lower NF conductor, an internal dielectric, a balun and an external dielectric. The lower NF conductor is electrically connected to the balun base on the end of the in-plug connector connection side and to the internal conductor of the plug-in connector on the open end of the balun.

Abstract: An improved HF coupler or HF power splitter comprises four connection lines arranged on the same side of the substrate. Two coupling zones are formed on the substrate on two opposite sides; the second coupling zone is connected to the associated connection lines arranged on the side of the substrate opposing the coupling zone, by means of two via holes in an electroplated manner. The capacitors provided at the beginning and at each end of each coupling zone are respectively embodied as interdigital capacitors; and the capacitors are respectively coupled to earth.

Abstract: The invention relates to an improved amplifier switch which for example has the following features: between an in-gate (1; 1.1, 1.2) and an out-gate (3; 3.1, 3.2) an amplifier branch (5; 5.1, 5.2) and at least one bridging line (7; 7.1, 7.2) that can be switched on and off in parallel thereto are provided. At the outlet side, an amplifier branch (5; 5.1, 5.2) is connected to a pertaining bridging line (7; 7.1, 7.2) via a summing circuit or a summing point (17) that is/are linked with the out-gate (3; 3.1, 3.2). The bridging line (7; 7.1, 7.2), between the pertaining switch contact (K1) of the pertaining switch (9; 9.1, 9.2) and the summing circuit or the summing point (17), has an electrical length that corresponds to ?/2.
