H. Miyake et al., A study of a laminated band elimination filter comprising coupled-line resonators using low temperature Co-fired ceramics, IEICE TR EL, E82C(7), 1999, pp. 1104-1109
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 inv
estigated. The performance is simulated and the improvement by staggered re
sonators is confirmed. An experimental filter made of Low Temperature Go-fi
red Ceramics (LTCC) is constructed. It shows good performance.
