General Description

The TAT8888 is an ultra-linear, packaged GaAs/GaN

amplifier intended for output stage amplification in

CATV infrastructure applications.

The TAT8888 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 TAT8888 draws 445

 mA from a +24 V supply and

exceeds the output linearity performance of traditional

GaAs-based amplifiers.

The TAT8888 is packaged in an industry standard 7-pin

SOT-115J module.
