A Study of a Laminated Band Elimination Filter Comprising Coupled-Line Resonators Using Low Temperature Co-Fired Ceramics

Coupling effects between resonators on a laminated Band Elimination Filter (BEF) is studied. The coupling degrades the filter attenuation performance. A new equivalent circuit of coupled-line BEF with loaded capacitors is investigated. The performance is simulated and the improvement by staggered resonators is confirmed. An experimental filter made of Low Temperature Co-fired Ceramics (LTCC) is constructed. It shows good performance. key words: band elimination lter, coupled-line resonators,
