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.
