Product Summary

The AD6600AST is a Dual Channel, Gain-Ranging ADC with RSSI. The AD6600AST includes two input channels, each with 1 GHz input amplifiers and 30 dB of automatic gain-ranging circuitry. The AD6600AST may be used as a stand-alone sampling chip, or it may be combined with the AD6620 Digital Receive Signal Processor. The device provides 10 dB–25 dB of additional processing gain before passing data to a fixed- or floating-point DSP. The applications of it are Communications Receivers, PCS/Cellular Base Stations, GSM, CDMA, TDMA, Wireless Local Loop, Fixed Access.
