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

can be biased from a single positive supply ranging from

3.3 to 5 volts. The device is housed in a green/RoHS-

compliant industry-standard 2x2 mm package.

8 Pin 2X2 mm DFN Package

Product Features

• 0.6-4.2 GHz Operational Bandwidth

• Ultra-low noise figure, 0.54 dB NF @ 3.5 GHz

• >20 dB gain across 1.5 to 3.8 GHz

• Flat 2.4 dB gain variation across 1.7 to 3.8GHz

• Bias adjustable for linearity optimization

• 32 dBm OIP3 at 50mA I_DD

• Shut-down mode pin with 1.8V logic

• Unconditionally stable

• Integrated shutdown control pin

The QPL9057 is internally matched using a high-

performance E-pHEMT process and only requires five

external components for operation from a single positive

supply: an external RF choke and blocking/bypass

capacitors and a bias resistor going to pin 1. This LNA

integrates a shut-down biasing capability to allow for

operation in TDD applications.

The QPL9057 is optimized for linear performance across

the 1.5 to 4.2 GHz frequency band but can operate down to

600 MHz.

• Maintains OFF state with high Pin over drive

• +3.3V to +5.25V single supply; does not require -V_GG
