Contextual Info: Low Noise, 90 MHz Variable Gain Amplifier AD603 Data Sheet The decibel gain is linear in dB, accurately calibrated, and stable over temperature and supply. The gain is controlled at a high impedance 50 MΩ , low bias (200 nA) differential input; the scaling is 25 mV/dB, requiring a gain control voltage of only
