I read the data sheets of ADC AD9434 and its FMC connector evaluation board (AD9434-FMC-500EBZ) and consider buying it. What worries me at the moment is the analog input filtering that seems to happen on the board. There are two inputs (AIN and AMPAIN) and I understand the the first one is passive and the second one active with possible gain but both seem to at least AC couple the signal. Would it be possible to get a transfer function of the two? Or a list of poles or so?
I assume a bandpass filter with flat passband from ~1MHz to ~1GHz or so. If so, I would be satisfied by the two correct numbers.
