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.
