Hello,
I am using AD9139 for the transmitter, the evaluation board uses two buluns, why use two balun? What's the effect of using only one? Thanks!

Hi Draogn,
Your query is acknowledged and will be responded by the product owner soon.

Hi Draogn ,
The two baluns in the DAC output data paths are for converting the differential output to single ended while suppressing the noise coming from the feedline (the 1:1 balun acts as an isolator). If using only one balun (i.e. the 1:2 balun only), SNR may not be optimal due to noise.
