Microwave Ceramics and Modules Filter
2 – Pole Filter for W - LAN B69812N2457E101
Preliminary Datasheet
ISSUE DATE 18.01.02 ISSUE P1 PUBLISHER SAW MWC PD F PAGE 1/4
Features
• Low Profile (maximum height 1.4mm)
• 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 / TCf =0±10 ppm/K) with a coating of copper (10µm) and tin (>5µm)
• Excellent reflow solderability, no migration effect due to copper/tin metallization
