A novel miniaturized high temperature superconductor (HTS) four‐pole filter for the Radio Frequency Interference Mitigation of the 900 MHz cellular band in radiotelescopes is presented. This circuit incorporates a new type of capacitive cross‐coupling between nonadjacent resonators to achieve a quasi‐elliptic response. Design procedure along with simulation and experimental results are shown. © 2009 Wiley Periodicals, Inc.
