| 摘要 |
The invention relates to a non- reciprocal circuit element (1) having a plurality of strip conductor elements (2) insulated electrically from one another, which conductor elements are embedded in a multilayer core (3) of ferrimagnetic material and are arranged in superposed conductor planes in such a way that the conductor elements (2) cross over one another in at least one crossover area (4, 5). To provide such a circuit element, which is particularly cost-effective to produce and which is suitable in particular for use in mobile phones, the invention proposes that the core (3) comprises, at least in the crossover area of the conductor elements (2), hard magnetic material, which is permanently magnetized in a spatial direction perpendicular to the conductor planes.
