Abstract
A technique relates to a lossless microwave switch discussed herein. Multiple ports are included in the lossless microwave switch. Tunable filters are included in the lossless microwave switch. Each of the ports is operatively coupled a corresponding one of the tunable filters.
Claims22
A lossless microwave switch comprising:
- a plurality of ports;
- and
- tunable filters, wherein each of the plurality of ports is operatively coupled to a corresponding one of the tunable filters, wherein the tunable filters are lossless low-pass filters.
A method of configuring a lossless microwave switch, the method comprising:
- providing a plurality of ports;
- and
- providing tunable filters, such that each of the plurality of ports is operatively coupled to a corresponding one of the tunable filters, wherein the tunable filters are lossless low-pass filters.
A lossless microwave switch comprising:
- a plurality of ports;
- and
- tunable filters, wherein each of the plurality of ports is associated with one of the tunable filters, wherein each of the tunable filters includes a superconducting quantum interference device.
A lossless microwave switch comprising:
- a node;
- and
- tunable filters connected to the node, wherein the tunable filters are configured to be independently tuned to a first state to transmit a signal and be independently tuned to a second state to block the signal, such that any one of the tunable filters is configured to transmit the signal to any other one of the tunable filters via the node.
