Abstract
The invention starts from a device for dividing high-frequency energy between two mutually decoupled outputs (A1, A2) with matched impedances, with a matching transformer (Ü1) and a differential transformer (Ü2) as well as a decoupling impedance. To achieve a broadband high decoupling of the two outputs (A1, A2) with good matching of all terminals in as simple and inexpensive a manner as possible, two possible circuits are proposed: In the first embodiment the decoupling impedance is an ohmic resistor (R1) which is connected between the connection point of the matching transformer (Ü1) and one of the two outputs (A1, A2) in the case of symmetrical distribution, and the output with the higher resistance in the case of non-symmetrical distribution, its magnitude and the location of the tapping being selected in such a way that both the decoupling of the two outputs (A1, A2) and the return loss have an optimum value at the output with the higher resistance. In the second embodiment of the distribution network according to the invention, the series circuit of an ohmic resistor (R2) and a reactance (L) with a resonant frequency of approximately 50 MHz is connected between the two outputs (A1, A2). <IMAGE>
