Cryogenic Filters for RFI Mitigation in Radioastronomy

RFI mitigation in Radioastronomy can be achieved adopting cryogenic filters in appropriate typologies. A study has been conducted in L, C and X band with the evaluation of the filt er architecture in copper, with theoretical estimation, co mputer simulations, prototypes realization, laboratory measure ments. Such work has been preliminary to the realization of HTS samples with the purpose of a similar complete characterization approach.
