摘要: This study presents the analysis and design of a new triple-mode filter that employs recently proposed triple mode conductor-loaded cavity resonator. The resonator consists cubic-shaped metallic structure suspended in enclosure. is mounted through low-loss low-dielectric-constant support structure. considerably cheaper, easier to manufacture, offers significantly wider spurious-free response comparison with dielectric A six-pole designed using Ansoft HFSS employing shows introducing asymmetry into form chamfers or corner cuts creates necessary perturbation achieve required coupling between degenerate modes inside each block realise desired response. fabricated tested. Finally, two applications concept are identified. combined higher Q-factor ceramic resonators small size, high wide Also, direct-coupled band-stop filter.
