A superconducting microwave selective filter system having a superconducting filter connected to receive RF signals and perform filtering before the RF signals are applied to nonlinear circuitry such as receiver protectors and low noise amplifiers. A single pole n throw point switch selects a desired one of the filters to provide a receiver with a desired frequency, such as an active radar frequency. The low loss and high dynamic range of a superconducting filter permits these filters to be employed in the front end of the system before system nonlinear circuitry.
