A High Selective HTS Filter with Group Delay Self-Equalization for 3G Mobile Telecommunication Systems

A recent development of a twelve-pole high-temperature-superconducting (HTS) bandpass filter with group delay self-equalization for 3G wireless applications is reported. The filter is designed to have a 5.425 MHz pass-band at a centre frequency of 2121.5 MHz. The filter exhibits a quasi-elliptic function response implemented with a cascaded quadruplet (CQ… CONTINUE READING
