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 650 mA from a single +12 V supply providing 21 dB gain with excellent linearity. Users may adjust the bias current with external voltage enabling 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 5 x 7 mm QFN package with exposed paddle (EP) beneath the device for thermal and electrical grounding. For applications requiri...
