Dear all,
I have a question about the output 3rd-order intercept point simulation frequency setting in up-conversion mixer. I hope anyone could correct me if I am wrong.
For example, my upmixer is with input IF, input LO and output RF.
For 1dB compression point simulation, I will give input IF=10MHz, input LO=1000MHz. Then I measure the output RF=1010MHz.
If I wanted to simulate the output 3rd-order intercept point, my this frequency setting was correct or not?
I will give input IF= 9MHz and 11MHz, input LO=1000MHz. Then I measure the main tone RF frequency=1011MHz and 3rd-order tone=1007MHz. Am I correct?
Thanks,
wccheng
