As I recall, several here have posted that the LO input to the DBM should be about 7 dBm.? That agrees with the following DBM tutorial I found online:
However, I also recall someone here mentioning that they measured the LO input as only a little over 10dB higher than the RF input during transmit.? The above tutorial recommends that the LO be about 20 dBm higher than the RF input.
What is the consensus here?? Is having the LO input to the dBM only 10 dBm higher than the RF input during transmit OK, or is the tutorial correct about needing a 20 dBM delta between the two for the best results?
