Description
The TriQuint TGA2801D-SG is an ultra-linear, packaged
power amplifier which operates from 40MHz to
1000MHz. The amplifier is packaged in a standard 16
lead SOIC package. The amplifier provides a flat gain
along with ultra-low distortion. It also provides a high
output power with a low DC power consumption. This
amplifier is ideally suited for use in CATV distribution
systems or other applications requiring high output
powers and extremely low distortion.
Evaluation Boards are available upon request.
