Qorvo® debuts high-performance small cell products
Aimed at 5G networks, Qorvo® has announced new power-efficient, small cell front-end devices for the sub-6 GHz wireless infrastructure market.

The small cell products significantly boost efficiency, enabling base station manufacturers to enhance existing 4G LTE infrastructure with greater bandwidth, coverage, throughput and capacity – particularly in high-density, high-traffic areas.

Strategy Analytics estimates that, “Driven by the explosive growth of emerging 5G networks, the number of new base station sectors deployed will double between 2018 and 2024. 5G relies on network architectures incorporating traditional macrocells and lower power small cells in sub-6 GHz and millimeter wave frequency bands.”

The latest Qorvo products include the Band 3 QPA9903 power amplifier (PA), the Band 8 QPA9908 power amplifier, and the QPL9098 4-6 GHz bypass ultra-low noise amplifier. The PAs offer 34% power added efficiency, enabling Power over Ethernet (PoE) small cell architectures targeted for deployments in high-traffic areas, such as subways, train stations, and stadiums or for high quality of service (QoS) enterprise in-building applications.

The PAs are easy to linearize using DPD algorithms and their performance is optimized for wideband, multicarrier signals versus a single 20 MHz carrier. The highly rugged PAs can handle high levels of signal mismatch at output – up to 20:1 Voltage Standing Wave Radio (VSWR). Rugged packaging withstands the impact of a wide range of challenging environments.
