Abstract
The increased bandwidth and sensitivity of the DSN maser-based receiver systems along with the increase in worldwide microwave spectrum usage have dictated the need for employing additional measures to protect these systems from RFI (radio frequency interference). Both in-band and out-of-band microwave signals at the input of the Deep Space Network (DSN) traveling wave masers (TWM) can adversely affect the maser performance in a variety of ways. Filters fabricated from superconducting materials operating below their superconducting transition temperature (T,) possess the most potential for providing the necessary RFI protection without degrading the system performance.
