ABSTRACT:
The invention relates to a radio power distributor. The distributor comprises a plurality of dividers D(i-1), D(i) . . . mounted in cascade-like manner and each having a primary branch A(i-1, A(i) . . . which is divided up into secondary branches, whereof one, the main secondary branch B(i-1) is connected to the primary branch A(i) of the following and whereof the others (C) are terminated on the utilization points. All the branches (C) are connected to the same point a of the line B of the same rank i by resistance members. This makes it possible to absorb the reflected powers in these lines when mismatchings occur, even when the latter are identical. A phase changer .phi. is optionally placed in the primary branch.
