General Description
The TAT2801 is a high power, high linearity GaAs MMIC
amplifier intended for output stage amplification in CATV
infrastructure applications. Featuring a single die design
and providing flat gain with low distortion, this amplifier
is ideal for use in CATV distribution systems requiring
high output powers and low distortion.
The TAT2801 draws 575 mA from a 12 V supply Bias
current and voltage may be adjusted externally to
optimize output performance for specific applications.
The TAT2801 integrates two TQP200002 ESD
protection devices that provide bi-directional protection
with very low leakage currents and extremely low
capacitance.
The TAT2801 is packaged in an industry standard 16 pin
SOIC WB package.

Note: ACPR performance measured using application circuit on pg. 3. ACPR performance at low output power levels is reflective
of the limitations of the source. A better test source is likely to result in significantly better ACPR performance at these power
levels.
