I am going to use the most resent and the fastest ADL5569 differential amplifier as a buffer at the output of DDS. Naturally my aim is to impose as lower as possible phase noise on the DDS output signal. But the ADL5569 datasheet does not contain any information about its residual phase noise and it is the case for other similar amplifiers.
I can suggest that the phase noise is low enough since such an amplifier utilizes SiGe process, but I do not have enough time to check that by myself.
Perhaps somebody could provide me and the community with measured or simulated data related to phase noise performance of ADL5569 or similar DA.
Thanks in advance.
Hi,I moved your question to its proper community RF and Microwave.Best Regards,Goz
