help：mixer phase noise in Ads with prj file

i upload the prj file, it is very simple setup in ads,
but with higher order harmonics for RF signal, gain
changes, and also phase noise seems not correct

thanks

hi , i have checked it

the gain is not decreasing , when u make the order high , but u meaure anpther component

plot the dbm(Vif) , u will find there is a harmonics at 0 -44 db , which it the RF baseband

, about the phase noise

i am checking it

khouly

yes, you are right , i made a mistake to use old equation to calculate gain, it is the sideband signal, thanks

i have checked the phase noise and it is wokrking if u make a very samll shift

it is working good , i made the IF to 100 hz

so wee need to know how to filter the mixing terms

khouly

ads can not know which component to demodulate, but thanks a lot for help

i think there is a way to write an equation to ignore the mixing terms

and u welcome
