Abstract (en)

[origin: US2003003814A1] An improved circuit for splitting or for joining radio-frequency powers, having a main line (7) which is connected between an input port (1) and a first output port (3), and having a branch line (11) which branches off from the main line at a branching point (9) and leads to a second output port (5), is distinguished in that a compensating element (61) is provided which, in particular, is adjustable or can be fitted and removed differently, and which can be varied, varying the capacitance of at least one capacitor (C1, C2, C3) which is connected in the branch line (11), and/or varying the electrical length of a spur line (37) which is coupled to the branch line (11), such that the change in the magnitude of the power which is tapped off also makes it possible to compensate at the same time for the resistance change which is caused by the change in the power split.
