JOSPHSON BAND PASS TO BAND STOP FILTER - A simplified explanation of the abstract

This abstract first appeared for US patent application 17543095 titled 'JOSPHSON BAND PASS TO BAND STOP FILTER

Simplified Explanation

The abstract describes a device that can switch between band pass and band stop filter modes and provide reflectionless or near reflectionless function. The device includes a filter circuit with a direct current superconducting quantum interference device (DC SQUID), which can be activated by varying the inductance of the DC SQUID. By applying flux bias to the DC SQUID, the device can switch between the two filter modes.

  • Device facilitates selective switching between band pass and band stop filter modes
  • Device provides reflectionless or near reflectionless function
  • Filter circuit includes a direct current superconducting quantum interference device (DC SQUID)
  • Filter circuit is selectively activatable by varying the inductance of the DC SQUID
  • Flux bias applied to the DC SQUID allows for switching between filter modes

Potential Applications

  • Telecommunications systems
  • Wireless communication devices
  • Radar systems
  • Signal processing applications

Problems Solved

  • Switching between band pass and band stop filter modes
  • Achieving reflectionless or near reflectionless function
  • Selective activation of filter circuit

Benefits

  • Improved performance and flexibility in filtering applications
  • Enhanced signal processing capabilities
  • Reduction in signal loss and interference


Original Abstract Submitted

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.
