ABSTRACT:
In a circulator/isolator device used in a cellular transmission network, a centering ring is used to position the garnets with respect to the center conductor, magnets and pole piece. The clamping action of the housing holds the unit together. Because the ring centers all components, additional fixtures are not needed and inaccurate "eyeballing" by the assembler is eliminated. The garnets are held in place during assembly by the centering ring thereby eliminating the need for adhesive or dielectric grease. 0
