Product Description
The Tri Quint TGA2803-SM is an ultralinear, packaged TIA/Gain Block which operates from 40MHz to 1000MHz. 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 Ro HS pliant.
