Features
Low Profile (maximum height 1.2 mm)
SMD filter consisting of coupled resonators with stepped impedances
Low losses
High attenuations at GSM (900, 1800, 1900) and UMTS bands
High attenuation at 2 times center frequency
Excellent reflow solderability, no migration effect due to copper/tin metallization
