Analog Bandwidth in AD9625 and Nyquist Zones

I wanted to ask about the new ADC AD9625. In the datasheet indicates an analog bandwidth of 3GHz and it says that we can use only up to the second Nyquist Zone. The maximum sampling rate is 2.5 GSPS. The first NZ at the maximum sampling rate would be up to 1.25 GHz and the second between 1.25 GHz and 2.5 GHz. So, the range between 2.5 GHz and 3 GHz is not possible to be used.

Is it right?

I need to use for my application up to 3 GHz, and it could be make using the third NZ. There is any way to do it?

Thanks a lot in advance.
