General Description
Pin Configuration
The TAT8804 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 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 requiring demanding VSWR tolerance
at high input overdrive conditions, an EVB with level
protection is available (TAT8804D1H-EBP).
