Abstract
A method of fabricating ferrite toroids used in ferrite phase shifters. The method employs fabrication techniques found in low temperature cofired ceramics (LTCC) tape technology and involves fabricating long rectangular through-holes, as is required by the toroid design, in layers of green ceramic tape and maintaining the integrity of the through-holes during a firing process wherein ferromagnetic ceramic oxide in the tape is converted to ferrite.
