Functional Description

The SL1914 is a bipolar, low noise AGC amplifier

designed primarily for application in satellite tuner front

ends. It contains a low noise input amplifier, an AGC

stage with a minimum of 30dB of gain control and a 75

Ohm output drive. It replaces all active circuitry in

conventional architectures.
