Abstract

1450811 Microwave circulators SIEMENS AG 5 Oct 1973 [30 Oct 1972] 46528/73 Heading H1W A microwave circulator having three connection lines 4 and in which a ferromagnetic body is subject to a constant magnetic field is provided with two open-ended lines 6 on each of the connection lines 4, the lines 6 being spaced apart by #/8 and the line nearest the junction is spaced therefrom by #/8, where # is the mean operational wavelength. The circulator can have #/4 matching sections 5. The lines 6 provide more convenient impedance adjustment in integrated circuit devices since they can be shortened more conveniently than lines 4 or sections 5.
