摘要：Means for generating signals by bringing four input signals in the microwaverange together, which signals are the sum and differences between various combinationsof the input signals, the means comprising waveguides arranged in a first and a secondparallel plane (10,11), located next to each other. The waveguides of the first plane (11)comprise parallel input ports (1-4) to a first (14) and a second magic T (16) in which thefour input signals are added in pairs, as well as waveguides (18, 19) by which the inputsignals added in pairs are supplied to the input ports of a third magic T (15) where theyare added to generate a first output signal, and subtracted to generate a second outputsignal. In the first and second magic T (14, 16) the four input signals are subtracted inpairs. The input signals subtracted in pairs are transferred to waveguides (20, 21, 28) inthe second plane (10) by which they are supplied to a fourth magic T (17) arranged in thesecond plane. In this magic T the signals are added, whereby a third output signal isgenerated.
