Qorvo QPL9547 0.1GHz to 6.0GHz Ultra Low-Noise LNA

Qorvo QPL9547 0.1GHz to 6.0GHz Ultra-Low-Noise LNA is a high-linearity, ultra-low noise amplifier optimized for 5G Massive MIMO (Multiple Input Multiple Output) applications. At 1.9GHz, the amplifier typically provides 19.5dB gain, +39dBm OIP3 at a 65mA bias setting, and a noise figure of 0.3dB. The QPL9547 LNA is biased adjustable and can be biased from a single positive supply ranging from 3.3V to 5.0V. The device also has a power-down control capability integrated into the die for Time Division Duplexing (TDD) applications.

The Qorvo QPL9547 is housed in a compact, industry-standard DFN8 package, and requires minimal external components to operate.
