General Description
The TAT7464 is a 75
RF Amplifier designed for use
from 50 MHz to 2600 MHz, addressing the CATV and
Satellite bands in a single part. The TAT7464 contains
two separate amplifiers for push pull applications. It
provides an easy means for adjusting bias current
allowing designers to optimize power consumption for
high efficiency applications. The TAT7464 is fabricated
using 6-inch GaAs pHEMT technology to optimize
performance and cost.

Mechanical Information
Package Information and Dimensions
This package is lead-free/RoHS-compliant. The plating
material on the leads is 100% Matte Tin. It is compatible
with both lead-free
(maximum 260 °C reflow
temperature) and lead (maximum 245 °C reflow
temperature) soldering processes.
The TAT7464 will be marked with a “TAT7464”
designator and an 8 digit alphanumeric lot code
(XXXXYYWW). The first four digits are the lot code
(XXXX). The last four digits are a date code consisting of
the year and work week (YYWW) of assembly.
Note: distortion data taken at
higher RF output level
