General Description

The TAT7461 is a 75 Ohm RF Amplifier designed for CATV applications to 1000 MHz. The balance of low noise and distortion provides an outstanding solution for drop and distribution amplifiers.

The TAT7461 is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. On-chip negative feedback provides excellent gain and return loss stability. 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.
