Product specification
SA5219
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 (1kâ¦) differential inputs. The output is 50⦠differential.
Therefore, the 5219 can simultaneously perform AGC, impedance
transformation, and the balun functions.
The dynamic range 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.
