Thank you very much for your answer.
It was very helpfull.
I use the IF port as the input signal and get output signal at RF port. So i asume that if the P1dB is 10 to 14dBm, there is no problem to use 7dBm signal as IF.
I will take into account the 3dB addition to the noise floor because of...
Hello.
I have to do some noise floor calculations and don't understand how to do it with mixer in the rf chain.
Lets take an example: The mixer is HMC558LC3B of Hittite. Conversion loss~ 8dB . LO to RF isolation ~ 40dB.
LO data : Power = 15dBm , Noise floor -135dBc/Hz = -120dBm/Hz
IF data ...
