Means of securing ferrimagnetic core in a microwave phaser

Claim 1

A mounting assembly for mounting a core of ferrimagnetic material in a waveguide of a high-power microwave phase-shifter comprising: a waveguide; a ferrimagnetic core mounted longitudinally within said waveguide; a plurality of heat-conducting elements positioned on two opposite sides of said ferrimagnetic core and extending longitudinally along said ferrimagnetic core with a predetermined clearance between said ferrimagnetic core and said heat conducting elements to allow for thermal expansion; a plurality of dielectric transformers, one bonded to each end of said ferrimagnetic core, completely covering the ends of said core and partially covering the ends of said heatconducting elements thereby limiting the longitudinal motion of said core with respect to said heat-conduCting elements; a plurality of dielectric keys inserted into a plurality of keyways, said keyways being positioned partially in said waveguide wall and partially in said heat-conducting elements and acting to restrict longitudinal motion of said heatconducting elements with respect to said waveguide; said ferrimagnetic core being restrained from motion in the sidewise direction by the heat-conducting elements, said ferrimagnetic core being restrained in the vertical direction by the top and bottom walls of said rectangular waveguide.
