General Description
The TAT7469 is a 75 Ω RF Amplifier designed for CATV
use, but capable of operation up to 1200 MHz. The
TAT7469 contains two separate amplifiers for push pull
applications. It is fabricated using 6-inch GaAs pHEMT
technology to optimize performance and cost. Each
amplifier contains on-chip active biasing. The bias
current set point of each amplifier is adjustable with a
single resistor from the input to ground.
