QPL9057 Description

Short technical summary and product information.

The Qorvo QPL9057 is a high-performance, flat-gain, high-linearity, ultra-low noise amplifier (LNA) operating from 0.6 to 4.2 GHz. It is designed to provide reliable performance in demanding applications.

Key electrical characteristics include an ultra-low noise figure of 0.54 dB at 3.5 GHz, a typical gain exceeding 20 dB across the 1.5 to 3.8 GHz bandwidth, and a gain flatness of 2.4 dB over the 1.7 to 3.8 GHz range. The amplifier also features a high linearity with a typical OIP3 of +32 dBm at a 50 mA bias setting. It operates from a single positive supply voltage of +3 V to +5 V and includes a shutdown mode pin for TDD applications.

Internally matched using an E-pHEMT process, the QPL9057 requires minimal external components for operation, including an RF choke, blocking/bypass capacitors, and a bias resistor. Its unconditional stability and bias adjustability for linearity optimization make it a versatile choice for RF front-end designs.

This LNA is suitable for various applications requiring high performance and low noise, such as in wireless infrastructure, defense systems, and test and measurement equipment.
