First claim
Opening claim text (preview).
What is claimed is: 1. A method of making a high Q material comprising: providing barium magnesium tantalate; and incorporating one of Ba 2 MgWO 6 , Ba 8 LiTa 5 WO 24 , Ba 3 LaTa 3 Q 12 , BaLaLiWO 6 , Ba 4 Ta 2 WO 12 , Ba 2 La 2 MgW 2 O 12 , Sr 3 LaTa 3 Q 12 , and SrLaTaO 12 into the barium magnesium tantalate to form a solid solution having a high Q value of greater than 12000 at about 10 GHz. 2. The method of claim 1 wherein the solid solution does not include tin. 3. The method of claim 1 wherein the solid solution contains at least 95% barium magnesium tantalate. 4. The method of claim 1 wherein the solid solution contains at least 97% barium magnesium tantalate. 5. The method of claim 1 wherein the solid solution has a dielectric constant of at least 25. 6. The method of claim 1 further comprising incorporating MgTa 2 O 6 into the barium magnesium tantalate. 7. The method of claim 1 wherein the solid solution has a Q value of greater than 17000 at about 10 GHz. 8. The method of claim 1 further comprising incorporating the solid solution into a cellular base station. 9. The method of claim 1 further comprising incorporating the solid solution into a millimeter wave filter. 10. The method of claim 1 further comprising incorporating the solid solution into a collision avoidance system. 11. The method of claim 1 further comprising incorporating the solid solution into a resonator or isolator. 12. A method of making a composite material, the method comprising: providing barium magnesium tantalate; and incorporating one of Ba 2 MgWO 6 , Ba 8 LiTa 5 WO 24 , Ba 3 LaTa 3 Q 12 , BaLaLiWO 6 , Ba 4 Ta 2 WO 12 , Ba 2 La 2 MgW 2 O 12 , Sr 3 LaTa 3 Q 12 , and SrLaTaO 12 into the barium magnesium tantalate to form a composite material having a high Q value of greater than 12000 at about 10 GHz. 13. The method of claim 11 wherein the composite material does not include tin. 14. The method of claim 11 wherein the composite material contains at least 95% barium magnesium tantalate. 15. The method of claim 11 wherein the composite material contains at least 97% barium magnesium tantalate. 16. The method of claim 11 wherein the composite material has a dielectric constant of at least 25. 17. The method of claim 11 further comprising incorporating MgTa 2 O 6 into the composite material. 18. The method of claim 11 wherein the composite material has a Q value of greater than 17000 at about 10 GHz. 19. The method of claim 11 further comprising incorporating the composite material into a cellular base station. 20. The method of claim 11 further comprising incorporating the composite material into a resonator or isolator.
