| Abstract(in English) | We have developed a high-temperature superconducting receiving filter with narrow bandwidth and frequency tunability for X-band weather radar systems to reduce interference between adjacent radar channels. To realize a filter with narrow bandwidt and low insertion loss is necessary to obtain high unloaded Q (Qu) resonator. Coupled microstrip line resonators with 1.5 times wavelength and odd mode resonance frequency were adopted to suppress the radiation loss and achieve a high Qu value. The developed HTS filter has 8-pole quasi-elliptic function resoponse for sharp skirt characteristcs and frequency tunability in weather radar frequency band by using dielectric rods. THe measured frequency response of the filter shows center frequency tunability of 9700-9800 MHz, pass bandwidth of 8 MHz, insertion loss of 2.0dB. |
