Abstract: Systems and methods for switching impedance are provided. In some aspects, a system includes first and second impedance elements and an impedance switch module, which includes a third impedance element coupled between the first and second impedance elements and a switch parallel to the third impedance element. The switch is coupled between the first and second impedance elements, and is configured to switch between an open configuration and a closed configuration. An electrical path is completed between the first impedance element and the second impedance element via the first switch in the closed configuration. The electrical path is not completed in the open configuration. A total impedance of the first impedance element, the second impedance element, and the impedance switch module is varied based on the switching between the open configuration and the closed configuration.
