2 – Pole Filter for W - LAN B69812N2457A111 Preliminary Datasheet

Features

? Low Profile (maximum height 1.1 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 (εr = 88 / TC f =0±10 ppm/K) with a coating of copper (10μm) and tin (>5μm)

? Excellent reflow solderability, no migration effect due to copper/tin metallization
