General Description

The TAT7461 is a 75 Ω 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.
