Abstract: A method of forming an integrated microstrip circulator includes translating a ferrite disc into an aperture in a dielectric substrate, securing the ferrite disc in the dielectric substrate with an adhesive to form a composite structure, and forming circuitry on an upper surface of the composite structure and forming surface mount contacts on a lower surface of the composite structure by metallizing the upper and lower surfaces of the composite structure.

Abstract: Disclosed herein are embodiments of high Q, temperature stable materials with low dielectric constants. In particular, a two-phase material can form based on the rutile phase of titanium oxide along with a spinel structure of ZnAl2O4. This material can have a dielectric constant below 15 which is simultaneously temperature stable.

Abstract: A method of forming a composite material for use as an isolator or circulator in a radiofrequency device comprises providing a low temperature fireable outer material, the low fireable outer material having a garnet or scheelite structure, inserting a high dielectric constant inner material having a dielectric constant above 30 within an aperture in the low temperature fireable outer material, and co-firing the lower temperature fireable outer material and the high dielectric constant inner material together at temperature between 650-900° C. to shrink the low temperature fireable outer material around an outer surface of the high dielectric constant inner material to form an integrated magnetic/dielectric assembly without the use of adhesive or glue.

Abstract: The disclosed technology relates to a ceramic composition and an article formed therefrom. A ceramic article for radio frequency applications is formed of a ceramic material having a chemical formula represented by: Bi1.0+aY2.0-a-x-2yCax+2yFe5-x-yMIVxVyO12 or Bi1.0+aY2.0-a-2yCa2yFe5-y-zVyInzO12. The ceramic material has a composition such that a normalized change in saturation magnetization (Δ4πMs), defined as Δ4πMs=[(4πMs at 20° C.)-(4πMs at 120° C.)]/(4πMs at 20° C.), is less than about 0.35.
