Impact of LO spurs on heterodyne chain
Most of us know from customer specs the level of spurs are defined (in e.g. from a LO fractional-N synthesizer), but I would like to know if someone could provide any paper showing the impact of high spurs on a heterodyne chain.
We know, the LO spurs can be translated (in e.g. up-converted) to a rx chain and affect the phase error, or increase the BER, specially when it hits the non-linear elements such as DBM-mixer, so the mixer, as multiplier, in addition with other desired signals can cause intermodulation effects on it.
Any paper is welcome. Thks.
