Our customer is asking, what is the lowest end of capable output frequency of ADL5380.

Subject to its datasheet, Specifications, I/Q BASEBAND OUTPUTS, Demodulation Bandwidth under 1V p-p signal, 3dB bandwidth is typically 390MHz, and also page 7. Figure 6. shows zero dB baseband response is crossing at 10MHz frequency.

The customer would like to know how is below 10MHz until DC region means ultimately 0Hz.

If you provide any data of the range from 0Hz to 10MHz output frequency, to show it's feasibility or incapability, it would be very much appreciated.
