Abstract:
1. A wideband circuit for splitting or joining radio-frequency powers, comprising: a main path connected between an input port and a first output port, the main path having an associated inner conductor; a branch line which branches off from the main path at a branching point and leads to a second output port, an inner conductor leading to the branch line second output port; a spur line coupled to the branch line, and a compensating element for splitting or joining radio-frequency powers together in different ways, the spur line being connected via a first capacitor to the inner conductor associated with the main path, and via a second capacitor to the inner conductor, which leads to the second output port, of the branch line, the capacitances of the first and second capacitors being variable, by means of the compensating element, which is adjustable or can be preselected differently, and/or can be installed or removed, wherein; the electrical length of the spur line being varied by means of the compensating element such that the change in the magnitude of the power which is tapped off or supplied also makes it possible to compensate for the resistance change caused by the change in the way in which the power is split or joined together.
