Title:
MANUFACTURING METHOD OF NONRECIPROCAL CIRCUIT ELEMENTS
Document Type and Number:
Japanese Patent JP3683213
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of thin nonreciprocal circuit elements incorporating capacitors.
SOLUTION: In the manufacturing method for nonreciprocal circuit elements, the ferrite material 1 is composed of sintered blocks of laminated thin ferrite sheets 2 and has flexibility in its shape making it easy to manufacture. Since the dielectric is made up by laminating insulation films on the ferrite material 1 and can be formed thin, it is possible to obtain a thin nonreciprocal circuit elements.
