Abstract: 852,799. Waveguide arrangements. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 15, 1958 [Dec. 16, 1957], No. 40326/58. Class 40(8). [Also in Group XL(c)] A time-dependent attenuator comprises a magic-T junction whose symmetrical arms each contain a ferrite variable phase-shifter and which are coupled by a 3db. directional coupler. The magic-T 1 is of the type in which the symmetrical arms 9, 10 lie side by side and have a common wall. The arms are coupled by a 3db. directional coupler 2 and contain transverse-field ferrite phase-shifters 3, 4. Input power applied at 15 is divided equally in phase quadrature between guides 9, 10 and, in the absence of any current in the phase-shifter field coils 5, 6, each portion of the signal suffers the same delay in the guides, The signal is recombined in the magic-T 1 and equal portions divided between the output branches 16, 17. If the field currents in coils 5, 6 are arranged to produce a differential phaseshift of #/2 between guides 9 and 10,the inputs to the magic-T will be in phase and the whole power will appear at the output 16. Conversely, a differential phase-shift of #/2 will divert the whole power to the output 17. If this is terminated by a matched load 18, the circuit behaves as a variable attenuator between terminals 15, 16 and a periodic variation of attenuation may be obtained by applying an alternating current to the coils 5, 6. The circuit may thus be used as a swept gain control in a radar receiver (see Group XL(c)).
