Description

The SA5219 represents a breakthrough in monolithic amplifier design featuring several innovations. This unique design has combined the advantages of a high speed bipolar process with the proven Gilbert architecture.

The SA5219 is a linear broadband RF amplifier whose gain is controlled by a single DC voltage. The amplifier runs off a single 5 volt supply and consumes only 40mA. The amplifier has high impedance (1k) differential inputs. The output of SA5219 is 50 differential. Therefore, the 5219 can simultaneously perform AGC, impedance transformation, and the balun functions.

The dynamic range of SA5219 is excellent over a wide range of gain setting. Furthermore, the noise performance degrades at a comparatively slow rate as the gain is reduced. This is an important feature when building linear AGC systems
