GaAs HBT VECTOR MODULATOR 1.8 - 2.7 MHz Application Circuit
10 T - SM S R O T A L U * Pins 15 & 16 are redundant I & Q inputs. 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: MOD G I G ( ,θ ) =Vmi + 1. V 0 Cos(θ ) G max G Q G ( ,θ ) =Vmq + 1. V 0 Sin(θ ) G max Where Vmi and Vmq are the I and Q voltage settings corresponding to maximum isolation at room temperature and F = 2 GHz. Gain Setting dB ( ) Note that G=10

where x = and y = . N Max G ain Setting ( dB) ominally Vmi = Vmq = 1.5V, Gmax = 0.316. 20 20 Information furnishe F d o b r pr y Analic o e g , D d evi e ce li s v i e s brey li , a eve n d t d to p o be acc luac rat e o e an r d d rele ia rs ble , p .
