The gain is unity and the output leads the input by 90°. The main advantage of this approach is that the output impedance of the circuit is low enough to drive the balanced modulator directly.

4.4.2.3 Balanced Modulator. A balanced modulator is a circuit which accepts two input signals of different frequencies, a carrier A cos mct and a modulating signal B cos fflst, and produces an output proportional to the product of the two inputs v0(t) = kAB cos oCt cos fflS t
