<P>PROBLEM TO BE SOLVED: To provide a ferrite-magnet element and a non-reciprocal circuit element that are operable in a plurality of frequency bands as one assembly. <P>SOLUTION: A ferrite-magnet element comprises: a single ferrite 32; a plurality kind of center electrodes that are each formed at least two regions in the long-side direction of the ferrite 32 and are corresponding to a plurality of frequency bands (for example, the 836 MHz band and the 1.95 GHz band); and a permanent magnet 41 that is fixed on a primary surface of the ferrite 32. The permanent magnet 41 applies DC magnetic field to the ferrite 32 and the plurality kind of center electrodes. <P>COPYRIGHT: (C)2013,JPO&INPIT |
