Abstract

2つのTM_<01δ>モード誘電体共振器をYBCO高温超伝導空洞の中心に同軸状に配置することにより、3dB帯域幅36MHzの12GHz帯帯域通過フィルタを構成した。このフィルタの高電力特性と高調波歪みを、超伝導体の部分を銅に置き換えた同型のフィルタと比較した。これらのフィルタは77Kにおいて5Wまで0.2dB以下の低損失性を維持し、10Wを越える耐電力性をもち、高調波妨害が100dBmとなることが実証された。

A narrow-bandwidth bandpass filter with a center frequency of 12GHz and a 3dB bandwidth of 36MHz is constructed by orienting two TM_<01δ> mode dielectric rod resonators in the center of a YBCO high-T_c superconducting bulk cylinder. The high-power and intermodulation characteristics of this filter is compared with those for a similar filter structure using a copper cylinder in place of the YBCO cylinder. This filter realizes the low-loss characteristic below 0. 2dB up to 5W, the high power-handling capability over 10W and the third-order intermodulation intercept of 100dBm at 77K.
