摘要
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. (C) 2009 Wiley Periodicals, Inc.
