TGA4928 High Linearity LNA Gain Block Applications Repeaters Mobile Infrastructure Defense/Aerospace LTE / WCDMA / EDGE / CDMA General Purpose Wireless IF amplifier, RF driver amplifier Military Communications Product Features Functional Block Diagram 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 General Description Pad Configuration The TriQuint TGA4928 is a high linearity Low Noise Pad No. Symbol Amplifier. The amplifier is fabricated using TriQuint s 1 RF Input TQPED process. It is internally matched and only 2 (Opt.) External Cap. requires an external RF choke and blocking/bypass 3 (Opt.) External Cap. capacitors for operation from a single +5V supply. The 4 RF Output / Bias internal active bias circuit also enables stable operation over bias and temperature variations. The TGA4928 covers the 0.054.0 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 Ordering Information epoxy only. Eutectic attach is not recommended. Lead-free and RoHS compliant Part ECCN Description High Linearity LNA TGA4928 EAR99 Evaluation Boards are available upon request.
