The diversity receiver, the AD6650, is a member of the MxFE family and is based on a mixed-signal design technique that partitions the signal path according to performance-enhancing, rather than analog/digital, boundaries. The chip integrates a digitally controlled VGA, an IF-to-baseband demodulator, analog low-pass filtering, and dual analog-to-digital converters. The AD6650 can accommodate IF input frequencies up to 70 MHz to 300 MHz and features a linear signal range of more than 106 dB and a dynamic range of more than 110 dB. Only one external SAW filter is required for the RX signal path to meet GSM/EDGE blocking requirements.
