Abstract

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.
