LTC5548 minimum input LO and X2 pin

Good day!

What is the minimum acceptable LO value I can enter into the mixer input without disrupting its operation?

Do I understand correctly:
Upmixer
IF = 1GHz
LO = 4GHz
X2 = High
RF = 9GHz?
Does the frequency doubling mode work in both upmixer and downmixer modes?

LTC5548's minimum LO drive level is -6dBm for both X2 disabled and enabled conditions. ADI do not guarantee performance or function below -6dBm.

You understanding of the LO doubling function is correct…

The LO frequency doubling function works in both upconversion and downconversion modes.
