designing of Gilber cell mixer circuit

Hello everyone,

I have design gilbert cell mixer. I have attached its schematic and simulation result please check if it is correct ?

No, it doesn't work.You have to drive LO and RF ports differentially.But you connected one of them to ground.

So how can i do that?



I think by giving opposite polarity signal on the negative side of LO and RF? I am completely new in this field please help me.
