    Qorvo's TGA2803-SM is an ultra-linear, packaged transimpedance amplifier (TIA) / gain block which operates from 40 MHz to 1000 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.

    The part is lead-free and RoHS compliant. Evaluation boards are available upon request.
