Abstract

A description is given of a combiner of signals at high frequencies (in the microwave range, particularly from about a hundred megahertz to tens of gigahertz), in which the ratio between the powers of the signals arriving at the output port and originating from two different input ports can be varied continuously, the said combiner comprising at least three hybrid circuits, of the 3 dB/90 degree type for example (ABC), a double fixed short circuit (E), a load (G) and a double moving short circuit (F) with a line of length L variable from 0 to <IMAGE>/4, the wavelength corresponding to the central frequency of the band. It is now characterized by a magic T and by a double moving short circuit which can be moved along two lines, each consisting of two sections of length L = <IMAGE>/4. (Fig. 4) <IMAGE>
