Microwave Device of Ceramic Resonator Type Having Excellent Attenuation Characteristic

摘要

PURPOSE: A small ceramic resonator-type microwave element is provided which passes frequencies of the GHZ band by an excellent function of reduction. The function of the reduction of the blocking band is improved by an attached simple bypass device. CONSTITUTION: The microwave element comprises an input terminal (35) which receives input signals, many ceramic resonators (20a-20h) which output signals of only series-connected frequency bands, one or more second ceramic resonators which are connected in parallel to one or more ceramic resonators, and an output terminal (36) which is connected to the last resonator and outputs output signals.
