General Description
Pin Configuration
The TAT9988 is an ultra-linear, packaged GaAs/GaN
amplifier intended for output stage amplification in
CATV infrastructure applications.
The TAT9988 features a push-pull cascode design
which provides flat gain along with ultra-low
distortion, making it ideal for use in CATV distribution
systems requiring high output power capability.
The TAT9988 draws 445mA from a 24V supply and
exceeds the output linearity performance of
traditional GaAs-based amplifiers.
The TAT9988 allows users to adjust the bias current
and the bias voltage externally in order to optimize
output performance.
The TAT9988 is packaged in an industry standard 40
pin 5x7 mm² QFN package.
