Product Summary

The AD603AR is a low noise, voltage-controlled amplifier for use in RF and IF AGC systems. It provides accurate, pin-selectable gains of -11 dB to +31 dB with a bandwidth of 90 MHz or +9 dB to 51+ dB with a bandwidth of 9MHz. The AD603AR can drive a load impedance as low as 100 Ω with low distortion. For a 500 Ω load in shunt with 5 pF, the total harmonic distortion for a ±1 V sinusoidal output at 10 MHz is typically-60 dBc. The peak specified output is ±2.5 V minimum into a 500Ω load. The applications of the AD603AR are RF/IF AGC amplifiers, Video gain controls, A/D range extensions, Signal measurements.
