The invention relates to an improved circuit for dividing or bringing together high-frequency performances. The inventive circuit comprises a main line (7) that is switched between an input and a first output port (1, 3) and a branch line (11) which branches off from the main line at a branch point (9) and leads to a second output port (5). The inventive circuit is characterised in that a balancing element (61) which is especially adjustable or can be especially built in or re-moved in different ways is provided. Said element can be changed by changing the capacity of at least one capacitor (C1, C2, C3) which is switched in the branch line (11) and/or by changing the electric length of a spur line (37) which is coupled to the branch line (11), in such a way that the resistance change that is caused by the changed performance division can be compensated when the variable of the branched off performance is changed.
