is about 10MHz. I want to know what the maximum signal bandwidth of AD9957 can
The maximum signal bandwidth is ~62MHz.
Given a 1GHz system clock, the AD9957's maximum vector(IQ) rate is 125MSPS.
Note, we recommend that the user up sample their baseband signal by a minimum
This is to avoid excessive roll-off of the 1st half band's frequency response.
I have seen applications around 56MHz.
