Applications Repeaters Mobile Infrastructure Defense/Aerospace LTE / WCDMA / EDGE / CDMA General Purpose Wireless IF amplifier, RF driver amplifier Military Communications TGA4928 High Linearity LNA Gain Block Product Features Frequency Range: 0.05 – 4.0 GHz NF: 2.1 dB (@ 1.9 GHz) Output IP3: +36 dBm (@1.9 GHz, 4 dBm/tone Pout) P1dB :+21 dBm (@ 1.9 GHz) Small Signal Gain: 14 dB (@ 1.9 GHz) +5V Single Supply, 85 mA Current Chip Dimensions: 1.49 x 0.85 x 0.085 mm Functional Block Diagram General Description 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. The TGA4928 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.
