“…The Toshiba Corporation has developed a HTS narrowband filter for both a transmitter and receiver of a weather radar application [112][113][114]. Because HTS filters have a relatively poor power handling capability, the filter for the transmitter had a hybrid structure which consisted of cavity resonators for high power handling capability and superconducting resonators for a sharp skirt characteristic [113,114]. The hybrid filter was specially designed to let the input signals at the center frequency come through the cavity resonators, while signals at the edges came through the HTS resonators.…”

In the past two decades, various kinds of high performance high temperature superconducting (HTS) filters have been constructed and the HTS filters and their front-end subsystems have been successfully applied in many fields. The HTS filters with small insertion loss, narrow bandwidth, flat in-band group delay, deep out-of-band rejection, and steep skirt slope are reviewed. Novel HTS filter design technologies, including those in high power handling filters, multiband filters and frequency tunable filters, are reviewed, as well as the all-HTS integrated front-end receivers. The successful applications to various civilian fields, such as mobile communication, radar, deep space detection, and satellite technology, are also reviewed.
