INTEGRATED CIRCUITS NE/SA5209 Wideband variable gain amplifier Product specification RF Communications Handbook 1990 Aug 20 Philips Semiconductors Philips Semiconductors Product specification Wideband variable gain amplifier NE/SA5209 DESCRIPTION The NE5209 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 NE5209 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 (1kΩ) differential inputs. The output is 50Ω differential. Therefore, the 5209 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.
