Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The QPL9057TR7 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/RoHScompliant industry-standard 2x2 mm package.

The QPL9057TR7 is internally matched using a highperformance 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.
