In the design of the evaluation board, you use the minicircuits ADT1-1WT as the output transformer. Contrarily to your suggestions in the datasheet and what I can see it was intended in the schematics, It is a 75ohm transformer. I have checked in different evalBaord I have, and all of them have the same.

 

Is there any reason for this? did i missed something?

 

Thanks and best regards,
