描述 Description

Qorvo's TGA4909 is a high linearity Low Noise Amplifier. The amplifier is fabricated using Qorvo's TQPED process. It is internally matched and only requires an external RF choke and blocking/bypass capacitors for operation from a single +5V supply. The internal active bias circuit also enables stable operation over bias and temperature variations.
The TGA4909 covers the 0.05-4.0 GHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
Die attach should be accomplished with conductive epoxy only. Eutectic attach is not recommended.
Lead-free and RoHS compliant.
Evaluation Boards are available upon request.
