Gain and Phase control are applied through the I and Q control ports. For a given linear gain (G) and phase (θ) setting, the voltages applied to these ports in all measurements are calculated as follows: G Cos (θ ) G max G Q (G,θ ) = Vmq + 1.0V Sin (θ ) G max I (G,θ ) = Vmi + 1.0V MODULATORS - SMT 13 Where Vmi and Vmq are the I and Q voltage settings corresponding to maximum isolation at room temperature and F = 2 GHz. Note that G=10X and Gmax = 10Y where x = Gain Setting ( dB ) and 20 y= Max Gain Setting( dB ) . 20 Nominally Vmi = Vmq = 1.5V, Gmax = 0.316.
