Adjustable resonant filter having superconductor resonator with active elements field effect control switchable superconductor/non superconductor providing two resonant frequencies
Adjustable resonant filter having superconductor resonator with active elements field effect control switchable superconductor/non superconductor providing two resonant frequencies
The filter has a superconducting resonator (2) with active elements (A1 to An) with a field effect control switchable as superconducting or non superconducting dependent on the temperature conditions. Switching between superconducting and non superconducting conditions provides two resonant frequencies.
