Abstract
One or more systems, devices and/or methods of use provided herein relate to a device that can facilitate selective switching between band pass and band stop filter modes and/or can provide reflectionless or near reflectionless function. A device can comprise a filter circuit coupled between a pair of ports and comprising a direct current superconducting quantum interference device (DC SQUID), wherein the filter circuit is selectively activatable by varying the inductance of the DC SQUID. Applying flux bias to the DC SQUID can allow for the switching between the band pass and band stop filter modes.
