Helical resonators containing high T c ceramic superconductors
Resonators are the single most important ingredient in microwave and radio frequency circuits. We have produced some helical resonators using a bulk Ba2YCu3O7 high Tc ceramic superconductor. These resonators, which operate at 77 K and cover the frequency range from 0.1 to 2.0 GHz, outperform their a...

| Zusammenfassung: | Resonators are the single most important ingredient in microwave and radio frequency circuits. We have produced some helical resonators using a bulk Ba2YCu3O7 high Tc ceramic superconductor. These resonators, which operate at 77 K and cover the frequency range from 0.1 to 2.0 GHz, outperform their all copper counterparts by at least a factor of 5 in unloaded Q. |
