QPL9057 Ultra-Low Noise Flat Gain Amplifier General Description The QPL9057 is a flat-gain, high-linearity, ultra-low noise amplifier in a small 2 x 2 mm surface-mount package. The LNA provides a gain flatness of 2.4 dB (peak-to-peak) over a wide bandwidth from 1.5 to 3.8GHz. At 3.5 GHz, the amplifier typically provides 22.8 dB gain, +32 dBm OIP3 at a 50 mA bias setting, and 0.54 dB noise figure. The LNA 8 Pin 2X2 mm DFN Package can be biased from a single positive supply ranging from 3.3 to 5 volts. The device is housed in a green/RoHS- Product Features compliant industry-standard 2x2 mm package. 0.6-4.2 GHz Operational Bandwidth The QPL9057 is internally matched using a high- Ultra-low noise figure, 0.54 dB NF 3.5 GHz performance E-pHEMT process and only requires five >20 dB gain across 1.5 to 3.8 GHz external components for operation from a single positive Flat 2.4 dB gain variation across 1.7 to 3.8GHz supply: an external RF choke and blocking/bypass Bias adjustable for linearity optimization capacitors and a bias resistor going to pin 1. This LNA integrates a shut-down biasing capability to allow for 32 dBm OIP3 at 50mA IDD operation in TDD applications. Shut-down mode pin with 1.8V logic Unconditionally stable The QPL9057 is optimized for linear performance across Integrated shutdown control pin the 1.5 to 4.2 GHz frequency band but can operate down to Maintains OFF state with high Pin over drive 600 MHz. +3.3V to +5.25V single supply does not require -VGG Functional Block Diagram Applications Repeaters / DAS Pin 1 Reference Mark Mobile Infrastructure LTE / WCDMA / CDMA / GSM 1 8 Vbias NC General Purpose Wireless 2 7 RF In RF Out TDD or FDD systems 3 6 NC Shut Down 4 5 NC NC Backside Paddle - RF/DC GND Top View Ordering Information Part No. Description 2500 pieces on a 7 Reel QPL9057TR7 QPL9057EVB-01 0.6-4.2 GHz Evaluation Board Datasheet, Rev.
