Microwave Ceramics and Modules
2-Pole Filter for W-LAN
Filter
B69812N2457A301
Data Sheet
Features
• SMD filter consisting of coupled resonators with stepped impedances
• extreme low losses
• high attenuations at GSM (900, 1800, 1900) bands
• stable performance over wide temperature range
• excellent reflow solderability, no migration effect due to copper/tin metallization
