TriQuint TAT8804 CATV Power Doubler

TriQuint TAT8804 CATV Power Doubler

TriQuint's TAT8804 CATV Power Doubler is an ultra-linear, QFN GaAs amplifier MMIC intended for output stage amplification in CATV infrastructure applications. The device 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. ESD protection is also provided at the output of the device. The TAT8804 draws approximately 650mA from a single 12V supply giving 21dB gain with excellent linearity. Users may adjust the bias current with external voltage, which enables the TAT8804 to be used in applications such as doublers or for lower power system applications. The TAT8804 is packaged in an industry standard 40 pin 5x7 mm QFN package with exposed paddle (EP) beneath the device for thermal and electrical grounding.
