1. According to the AD 9371 DS, The transmitter O/P Impedance is 50 Ohm differential hence Balun has to be 1:1 Balun, In this case mini circuits 1:1 Balun (TCM1-83X+) is used in reference schematic which is fine and understood
2. According to AD 9371 DS, The Rx I/P and OBS Rx I/P Impedance is 200 Ohm differential, hence the balun has to be 1:4, But in the reference schematic BALUN is 1:1 (TCM1-83X+)is used, How this can be? Please Suggest us
3. The same applies for sniffer Rx I/P Impedance 400 ohm differential and the same BALUN is used.
4. Please suggest some balun for sniffer path.
