My work is to design a current mode mixer with current input and current output. However, all examples are voltage mode. Does anybody know how to simulate current mode mixer?
 

I believe that LO power is making the mixer in current mode
I agree that input and output are voltage / power mode.
This is because of 50 ohm impedance for both input and out put side.
If you do not folow the same impedances then I guess it called as current mode.
 

I update ic5141_base to user610, change the pdk and select mmsim610, the problem is solved.
Thanks!!!

sorry! Above is for another question. For current mode mixer, I simulate it with a v-i and a i-v convertor.
