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.
