General Description
The TriQuint TGA2803-SM is an ultra-linear, packaged
TIA / Gain Block which operates from 40 MHz to
1218 MHz.
The TGA2803-SM typically provides flat gain along with
ultra-low distortion. It also provides high output power
with low DC power consumption.
This amplifier is ideally suited for use in CATV
distribution systems or other applications requiring
extremely low noise and distortion.
Demonstration Boards are available.
Lead-free and RoHS compliant.
