Title:
CIRCUIT MODULE
Document Type and Number:
WIPO Patent Application WO/2011/083792
Kind Code:
A1
Abstract:
Provided is a circuit module on which a plurality of irreversible circuit elements having no yoke are mounted, in which magnetic coupling is prevented from occurring between the irreversible circuit elements. Core isolators (30a, 30b) are not disposed in such a manner that magnetic fluxes (φ1, φ2) are arranged in the state in which the direction of the magnetic flux (φ1) and the direction of the magnetic flux (φ2) are set to be the same direction. Specifically, the core isolators (30a, 30b) generate the magnetic fluxes (φ1, φ2) from left to right. The core isolators (30a, 30b) are arranged obliquely with respect to the magnetic fluxes (φ1, φ2). Therefore, the magnetic flux (φ1) is prevented from penetrating the core isolator (30b) in the state in which the direction of the magnetic flux (φ1) is set to be the same direction as the magnetic flux (φ2) (or the magnetic flux (φ2) is prevented from penetrating the core isolator (30a) in the state in which the direction of the magnetic flux (φ2) is set to be the same direction as the magnetic flux (φ1)).
