I've been working with the following IQ Modulator: http://www.hittite.com/content/documents/data_sheet/hmc496lp3.pdf
In any case, the data sheet states "Signal lines should have 50 ohm impedance...". All input lines are differential on the part. Does this 50 ohm impedance mean single ended? This is what I assume but it never states this explicitly. I'm wondering if I need to divide the amount by two to obtain the actual single ended input impedance.
