The AD6650 is a diversity intermediate-frequency-to-baseband (IF-to-baseband) receiver for GSM/EDGE. This narrow-band receiver consists of an integrated DVGA, IF-to-baseband I/Q demodulators, low-pass filtering, and a dual wideband ADC. The chip can accommodate IF input from 70 MHz to 260 MHz. This receiver architecture is designed such that only one external surface acoustic wave (SAW) filter for main and one for diversity are required in the entire receive signal path to meet GSM/EDGE blocking requirements.
