DEARS.

It seems that Single End output is possible in TRF3722 EVM schematic.

If can use Single End for LO_OUT in TRF3722? If yes, how should we make up schematic?

Answer please.

Yes, you can use the LO_Out single -ended. Simply AC couple to 50 ohm load on the unused port. --RJH

I also plan to do this. I assume the output must be biased to 3.3V to make this work? I think it says these are open collector outputs?
