Hi,

Do you have any idea about dual band GSM filters like one passband around 900 MHz and other passband around 1800 MHz? Where can I find such a component?

Actually I am also curious how cell phones operate dual band?

Thanks,

I guess at cell phones you have two different RF chains. At least when i do dual band GSM repeater it was designed that way.
