SUSPENDED DIELECTRIC COMBLINE CAVITY FILTER

摘要

A combline filter has a ceramic resonator disposed inside at least one cavitywall. Because the resonator is implemented as a hollow rod, a tuning element may be inserted into an opening on 5 the top ofthe rod to tune its frequency. A mounting element, inserted into an opening on the bottomofthe rod secures its position inside a cavity resonator. Instead of soldering the resonator to the filter's walls, the resonator is supported above a bottom or side wall of the cavityresonator.
