    Math for balanced mixer...

    Hi Lewish, My approach to model the balanced mixer would be to go all the way to the diode equation. A single diode mixer would look like I = esp(qV/nkT) - 1, where V is your A + B. Let's let qV/nkT = x. Then the equation for the balanced mixer would be: I = [exp(x) - 1] + [exp(-x) -1] For...
