General Description
The TAT3814 is a variable gain return path amplifier
designed for head-end and system amplifier
infrastructure applications. The TAT3814 provides up
to 37 dB gain with 20dB automatic gain control
capability.
The small size, 6x6 mm and efficient power dissipation,
nominal 2.5 watts, provide an ideal solution for high
density head-end applications and compact system
amplifiers.
Standard supply voltage for the TAT3814 is +8V.
Operation from lower supply voltages is possible.
Contact TriQuint CATV applications for guidance.
The TAT3814 is fabricated using 6-inch GaAs pHEMT
and HBT technologies to optimize performance and
cost.
