Gain and Phase control are applied through the I and Q control ports. For a given linear gain (G) and phase () setting, the voltages applied to these ports in all measurements are calculated as follows: MODULATORS - SMT 10 G Cos ( ) G max G Q (G, ) = Vmq + 1.0V Sin ( ) G max I (G, ) = Vmi + 1.0V 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.
