I am developing a evaluation board for AD9910. For the output before the filter cicuit a center tap RF transformer ADT1-1WT is required. But due to its unavailability in my proximity I am looking for an alternate transformer.
I am moving your question to the DDS forum, they should be able to assist you with your question.
If you are looking for a suggestion for an alternate transformer, I don't have one handy. If you have the specs for the given transformer, use that as a basis to find an alternate.
