When I simulate a Gilbert double balanced mixer,it seems the higher the IF,the lower the gain.But I think during the mixing process,the mixer quad(in Gilbert Cell )just operates as switch and the mixing product will be independent on the value of the IF.
So does the value of the IF affect the mixing process?Or the lower gain is just due to the output match??
