The suggested RF baluns for the TRF371125 are 1:1 (50-ohm/50-ohm). I'm operating at 3 GHz and there doesn't seem to be much of a selection available with good amplitude and phase balance. I have found some 1:2 baluns with better performance. Would it be okay to use a 1:2 balun and feed the RF input with 100-ohm differential instead of 50-ohm?
Does anyone know what is the differential input impedance of the MIXinp/MIXinn port at 3 GHz?
