The AD8370 has a measured gain is 2 dB higher than the calculated gain given in the datasheet. I have 100 ohms differential input to a balun that changes it to 200 ohms differential. The output has a balun that goes from 100 ohms differential to 50 ohms unbalanced.

Hi,

I moved your question about AD8370 here in RF and Microwave community. Someone from here will be able to help you.

Regards.
