The AD8366 is a dual, digitally controlled baseband amplifier that is designed to mate with the IQ outputs of the demodulators. This allows for the signal to be properly scaled relative to the full scale swing of the Analog to Digital converter. Also all of the IQ demodulators from Analog Devices can DC couple into the AD8366 which has a DC offset cancellation loop to prevent saturation of the desired signal. The AD8366 also has high levels of second and third order harmonic rejection (>88dBc).
