PRODUCT DESCRIPTION
The AD6650 is a diversity, 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 frequencies from 70 MHz to 300 MHz.
This receiver architecture is designed such that only one
external SAW filter(one for main and one for diversity) is
required in the entire Rx signal path to meet GSM/EDGE
blocking requirements.
Digital decimation and filtering circuitry is embedded on chip
to generate serial output I&Q
data streams.
The decimating
filters remove unwanted signals and noise outside the channel
of interest. In addition, programmable RAM Coefficient
filters allow anti-aliasing, matched filtering, and static
equalization functions to be combined in a single, cost-
effective filter.
The AD6650 is part of a complete GSM/EDGE receive and
transmit chipset. Other components in this chipset are: RF to
IF amplifier/mixers, receive and transmit frequency hopping
synthesizers, and a baseband to IF transmit modulator and
ramping chip.
