if i use an amplifier in front of a DDS (in my case AD9915) what would be the affect on SFDR and phase noise of DDS due to the SFDR and phase noise of amplifier...? i want to amplify the output of DDS without degrading its phase noise and SFDR..i need some sort of numerical calculations so that i can choose required amplifier
