Features
SMD filter consisting of coupled resonators with stepped impedances
extreme low losses
High attenuations at GSM (900, 1800) and UMTS bands
High attenuation at 2 times center frequency
(NdBa)TiO3 (εr = 88/TCf = 0 ±10 ppm/K) with a coating of copper (10
µm)
and tin (>5
µm)
Excellent reflow solderability, no migration effect due to copper/tin metallization
ESD insensitivity and ESD protecting due to filter characteristics
