<P>PROBLEM TO BE SOLVED: To provide a downsized magnetic resonance type isolator capable of adjusting input and output impedance. <P>SOLUTION: The magnetic resonance type isolator includes: a ferrite 10; a connection conductor 15 that is provided on the ferrite 10 and that includes openings P1, P2 and P3; a permanent magnet that applies a direct-current field to the ferrite 10; a capacitor C1 (or inductor) that functions as a first reactance element; and capacitor C2 (or inductor) that function as a second reactance element. A main line arranged between the first opening P1 and the second opening P2 of the connection conductor 15 does not resonate and an end of a sub-line branched from the main line defines the third opening P3. The deflected wave from the sub-line is adjusted to be shifted in phase by 90 degrees at the intersection with the connection conductor 15. The capacitor C1 is connected to the third opening P3, and the capacitor C2 is connected to between the first opening and the second opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
