GENERAL DESCRIPTION

The AD6659 is a mixed-signal, dual-channel IF receiver supporting radio topologies requiring two receiver signal paths, such as in main/diversity or direct conversion. This communications systems processor consists of two high performance analog-todigital converters (ADCs) and noise shaping requantizer (NSR) digital blocks. It is designed to support various communications applications where high dynamic range performance and small size are desired.
