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.
