Hi,
I have a frequency mixer of gain = 7 dB (at frequency which I need). His PLO = -5dBm, PRFIN = -23dBm. At the output of the mixer (RF output), the power is 5 dBm. I would like to calculate the power level at the mixer's inputs.
I am thinking that maybe the power at each of the two mixer inputs is -2 dBm (5 dBm-7dB=-2 dBm). But it's only a guess. I am not sure if I have to include some other parameters like the minimum power that the mixer needs for functioning, noise figure, IIP3, conversion power gain…. to find the power's at each of the mixer's inputs ( IF and LO)? And would the power at each of the 2 inputs (IF and LO) be the same or different ?
So I am asking for some help to find them ?
Thank you
