Qorvo, a leading provider of innovative RF solutions that connect the world, introduced a family of high-performance low noise amplifiers (LNAs) tailored for base station infrastructure deployments including 5G massive MIMO (m-MIMO). Qorvo’s newest family of LNAs combines an ultra low noise figure: 0.3 dB achieved at 2 GHz – with unmatched reliability and scalability in a very compact footprint.
The flagship QPL9547 LNA utilizes Qorvo's latest generation enhancement-mode pseudomorphic High Electron Mobility Transistor (pHEMT) process to provide market-leading noise figures and improved receiver sensitivity for cellular base stations. This LNA is internally matched and is available in a compact, 2 mm x 2 mm package to provide space savings for system designers. Additional LNAs in the product family such as the QPL9057, QPL9058, and QPL9504 are optimized to provide high gain and disable pins required for 5G wireless infrastructure.
In 5G networks, the uplink is the limiting factor, and massive MIMO makes the uplink even more critical. A combination of low noise figure and high dynamic range is the key to maximizing the coverage of a 5G network. The release of these third-generation LNAs makes it easier for our customers to design and deploy their 5G solutions. This LNA family helps ensure that data transfer will be seamless and reliable, prompting customer demand worldwide.
The QPL9547, QPL9057, QPL9058, and QPL9504 are in production now and are available for immediate delivery.
