Microwave Properties of Lithium Ferrites (Short Papers)

Low-power loss and high-power threshold properties have been measured between 3.0 and 17.2 GHz on three Li-Ti ferrite compositions of magnetizations 1250, 2250, and 3600 G. In each composition the use of cobalt resulted in a linear increase in mu₀ and h_crit. Temperature measurements were performed at 9.2 GHz on the 2250-G material. An illustration of how the data might be applied is given.
