Abstract

A high-frequency signal combiner comprises at least one first bridge coupler for the transformation of two input-end, first high-frequency signals into at least two output-end, first high-frequency signals in each case with identical power, and a second bridge coupler for the transformation of four input-end, second high-frequency signals, in each case with identical power, into an output-end, second high-frequency signal, of which the power corresponds to the summated power of the four input-end, second high-frequency signals. In this context, the four input-end, second high-frequency signals are each supplied from one output-end, first high-frequency signal. In order to add an integer multiple of four high-frequency signals, a cascade of second bridge couplers is realized with a number of cascade stages corresponding to the integer multiple. In every cascade stage, every second bridge coupler of the preceding cascade stage is replaced respectively by four second bridge couplers.
