Abstract
A dual operation mode all temperature filter is provided. The dual operation mode filter is provided with a housing defining at least two cavities, an input port and an output port. It is also provided with a non-superconducting resonator disposed in a first one of the cavities and a superconducting resonator disposed in a second one of the cavities. The second resonator comprises a superconducting material containing 8-15% silver. The dual operation mode filter filters at a relatively high level at temperatures below a threshold temperature and at a lower, conventional level, at temperatures below the threshold.
Claims10
A filter comprising:
- a housing defining at least two cavities, an input port, and an output port;
- a first non-superconducting resonator disposed in a first one of the cavities;
- and
- a first superconducting resonator disposed in a second one of the cavities.
1 more element
In combination,
- a dual operation mode filter providing a first level of filtering at temperatures below a threshold temperature and providing a second level of filtering at temperatures above the threshold temperature, the first level being higher than the second level;
- and
- a conventional filter cascaded with the dual operation mode filter.
