mixer phase noise
hi freinds,
i have a question about the relationship between the phase noise noise of the local oscillator and its impact on the output of the mixer in a radio receiver chain.
in fact, do we take in account the phase noise of the LO when calculating the noise figure ?
what are, if they exist, the requirements of the mixer that have to be fulfilled to avoid the impacts of phase noise on the mixer output?
lets take an example in which a local oscillator has a BAD phase noise factor ( without conscidering any numerical values) , so when we qualify it as BAD, what is the direct impact on the output of the mixer
thanks for any kind of help
regards
