A method includes depositing a first metal layer on a semiconductor substrate; etching the first metal layer to form a first electrode having a first lead; depositing a piezoelectric layer on the semiconductor substrate and first electrode; etching the piezoelectric layer to a shape of the gyrator to be formed within the circulator; depositing a second metal layer on the piezoelectric layer; etching the second metal layer to form a second electrode having a second lead, the second electrode being positioned opposite the first electrode, wherein the first lead and the second lead form an electrical port; depositing a magnetostrictive layer on the second electrode; etching the magnetostrictive layer to approximately the shape of the piezoelectric layer; depositing a third metal layer on the magnetostrictive layer; and etching the third metal layer to form a metal coil that has a gap on one side to define a magnetic port.
