ABSTRACT:
A device for generating signals by bringing four input signals in the microwave range together, which signals are the sum and differences between various combinations of the input signals, has waveguides arranged in a first and a second parallel plane, located next to each other. The waveguides of the first plane have parallel input ports to a first and a second magic T in which the four input signals are added in pairs, as well as waveguides by which the input signals added in pairs are supplied to the input ports of a third magic T where they are added to generate a first output signal, and subtracted to generate a second output signal. In the first and second magic T the four input signals are subtracted in pairs. The input signals subtracted in pairs are transferred to waveguides in the second plane by which they are supplied to a fourth magic T arranged in the second plane. In this magic T the signals are added, and a third output signal is generated.
