TriQuint TAT9988 CATV GaN Power Doubler
TriQuint's TAT9988 CATV GaN Power Doubler 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. This devices 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. It is packaged in an industry standard 40 pin 5x7mm2 QFN package.
