    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  ,
      

      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)…
