Qorvo has announced new power-efficient, small cell front-end solutions for the sub-6 GHz wireless infrastructure market. The products - QPA9903, QPA9908, and QPL9098 - 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.
With 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 new Qorvo solutions 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 Digital Pre-Distortion (DPD) algorithms and their performance is optimized for wideband, multi-carrier signals vs a single 20 MHz carrier. The highly rugged PAs can handle high levels of signal mismatch at the output – up to 20:1 Voltage Standing Wave Radio (VSWR). Rugged packaging withstands the impact of a wide range of challenging environments.
Qorvo is paving the path to 5G by helping to define 5G standards as a delegate to 3GPP and through collaboration with wireless infrastructure manufacturers, network operators, chipset providers, and smartphone manufacturers. Qorvo has helped conduct dozens of 5G field trials, and Qorvo’s 28 GHz products supported the Samsung 5G MIMO demo at the 2018 Winter Olympics.
Qorvo is showcasing its leading portfolio of advanced RF solutions at IMS 2019 from June 4-7, in Booth 806, at the Boston Convention & Exhibition Center.
