Features
Low Profile (maximum height 1.4 mm)
SMD filter consisting of coupled resonators with stepped impedances
Low losses
High attenuations at GSM (900, 1800) and UMTS bands
High attenuation at 2 times center frequency
(NdBa)TiO3 (
r = 88 / TCf =010 ppm/K) with a coating of copper (10
m) and tin (>5
m)
Excellent reflow solderability, no migration effect due to copper/tin metallization
