PURPOSE:To ensure the working of the titled isolator over the wide band frequencies, by setting two central conductors having a 90 angle between their longer axes and a ferrimagnetic material between two sheets of soft magnetic materials and setting the magnetostatic field vertical to the face of the ferrimagnetic material. CONSTITUTION:The reticulate center conductors 10 and 11 are insulated to each other by means of a thin sheet-like insulated material 12 such as mylar. A ferrite disk 13 is set contiguously to the conductor 11. Then a magnet 14 is provided at a single side of the upper part of the above-mentioned product via a soft magnetic material 19. At the same time, another soft magnetic material 19 is provided at the lower part of and contiguously to the conductor 10. An end of each of the conductors 10 and 11 is connected to a shielding case 15 which encloses the conductors 10 and 11, the disk 13 and the magnet 14. Thus an element earth face is obtained. This element is partially enclosed by a mild iron member 16 to form a feedback path in terms of a magnetic field circuit. This contributes to the miniaturization of the magnet 14. Furthermore, the nongrounded end parts of the conductors 10 and 11 are drawn out of the case 15 and then connected to each other by means of a resistance 17. |
