Abstract
A HTS switch includes a HTS conductor for providing a superconducting path for an electrical signal and an serpentine wire actuator for controllably heating a portion of the conductor sufficiently to cause that portion to have normal, and not superconducting, resistivity. Mass of the portion is reduced to decrease switching time.
Claims17
A high temperature superconducting (HTS) microwave switch comprising:
- HTS conductor means for providing a superconducting path for a microwave signal, said means including a switching portion having a reduced cross-sectional area relative to the remainder of said conductor means;
- actuation means for controllably heating said portion of said conductor means sufficiently to cause said portion to have normal, and not superconducting, resistivity;
- and
- second conductor means spaced from and parallel to said HTS conductor means, said HTS conductor means and said second conductor means comprising a transmission line for said microwave signal;
- whereby said switch transmits the signal when said actuation means is not heating said portion, and reflects the signal when said actuation means is heating said portion.
