FERRITE-CERAMIC RADIO FREQUENCY ATTENUATOR.
Abstract
Five alternate versions of suitable ferrite ceramic RF attenuators were developed in ful fillment of the contract. Each alternate, a ferrite core coated with various materials, attenuates RF energy and will protect electro explosive devices from spurious initiation. The ferrite material developed is optimum. The ferrite's properties achieved border the state of the art and are considered unimprovable at present. A ferrite with a permeability of 5,500 = 550 and a resistivity of 3 = 1 ohm-cm was achieved and reproduced. The five types of coatings prepared for the attenuator have various capacitances. Each of three coating types include silicon monoxide layers ... silicon monoxide has a dielectric constant of approxi mately 6. Ba m titanate (dielectric constant greater than 300) and titanium dioxide (dielec tric constant 100) offer higher capacitance. (Author)
