TGA4928 - TriQuint Semiconductor

TGA4928 High Linearity LNA Gain Block

The TriQuint TGA4928 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. Th.
