ANALOG DEVICES AN-502 handbook
The AD6600 is a dual-channel, gain-ranging ADC with RSSI, designed for IF sampling in superheterodyne receivers. It supports up to 20 MSPS sampling and 250 MHz analog input with 60 dB SFDR. The device includes on-chip attenuators, a peak detector, and an 11-bit ADC. It is intended to simplify receiver design by digitizing at the IF stage, reducing analog complexity and improving manufacturability.
The AD6600 uses a phase-compensated attenuator stage and an external LC filter to manage bandwidth and noise. Its RSSI function automatically adjusts attenuation based on signal strength, providing 6 dB of headroom to prevent clipping. The ADC output can be interpreted as a floating-point word for further digital processing.
