TAT3814

TAT3814

5 - 300 MHz Variable Gain Return Path Amplifier

Qorvo's TAT3814 is a variable gain return path amplifier designed for head-end and system amplifier infrastructure applications. The TAT3814 provides up to 36dB gain with 20dB automatic gain control capability. It supports DOCSIS 3.0 channel bonding applications.

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 Qorvo CATV applications for guidance.

The TAT3814 is fabricated using 6-inch GaAs pHEMT and HBT technologies to optimize performance and cost-effectiveness.
