Functional Block Diagram
General Description
The TriQuint TGA4909 is a high linearity Low Noise
Amplifier. The amplifier is fabricated using TriQuint'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.
