Hi Rob, I have used the same Balun recommended in guidelines i.e. "B0430J50100A00". The max input power at primary of the Balun would be 5.78 dBm single ended. I have an option to decrease the level if needed. As I understand from above, I have to include a 100 ohm DIFF Termination near ADC to reduce reflections. Where should I place the DIFF Temination i.e. After AC-coupling capacitor or before AC-coupling capacitor ? Sequence of placement in current test setup is PLL - Filter - Balun - AC coupling capacitor - "Long Trace 2.5 inch" - ADC. Thanks & Regards, Santanu Kumar Sinha
