Hello,

I am using ADF4356 for ADMV1013/14. I just found out the max RFOUT power for ADF4356 is -2 dbm at 6.8GHz. ADV1013/4 requires LO input is within -6 to 6 dbm. What will happen if LO power is less than -6dbm? Let's say LO input at ADMV1013 only sees -10dbm due to path loss?

Thank you,

Bao

Hi, The ADMV1013 should still work (i.e there will be conversion gain) but at a decreased level along with decreased linearity (OP1dB and OIP3). At 25C there will be only a small difference in conversion...
