Abstract

2個のTM_<01δ>モード誘電体共振器を空洞内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,高電力特性と相互変調歪みの測定を行った。誘電体をMgOの放熱棒で支持することにより耐電力性が2倍高くなり、77Kにおいて10Wまで0.2dB以下の低損失性を維持し,20Wを越える耐電力性をもち、相互変調妨害が100dBmとなることが実証された。

A narrow-bandwidth bandpass filter with a center frequency of 12GHz and 3dB bandwidth of 36MHz is constructed by orienting two TM_<01δ> mode dielectric rod resonators in the center of a cavity. The dielectric rods were supported by thin MgO rods with good thermal diffusion. to increase the power handling capability. This filter realizes the low-loss characteristic below 0.2dB up to 10W, the high-power handling capability over 10W and the third-order intermodulation intercept of 100dBm at 77K.
