    Qorvo's TAT7461 is a 75 Ohm RF amplifier designed for CATV applications to 1000 MHz. The balance of low noise, excellent distortion, and high-gain is applicable for drop and other distribution amplifiers.

    The TAT7461 is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. It provides consistent gain and return loss from the use of extensive on-chip negative feedback. The TAT7461 also uses an on-chip active bias for consistent bias current and repeatable performance. Simple external tuning allows the TAT7461 to achieve excellent return loss.
