PRODUCTION ENGINEERING MEASURE YIG SPHERES AND LIMITERS.
Abstract
Techniques making use of a heat treating process for adjusting the 4pi M sub s and linewidth values of GaYIG spheres have been tested and used to reduce the linewidth and control the 4pi M sub s where close tolerances are imposed. Further study of the frequency instability encountered upon subjecting the L band limiters to a varying temperature environment were found to be primarily due to the anisotropy field in the GaYIG material. Two batches of pure YIG and five batches of substituted YIG material were fired utilizing presintered garnet in place of the yttrium and iron oxides used prior to the previous reporting period.
