Qorvo, a leading provider of RF solutions for mobile, infrastructure, and aerospace and defense applications, introduces two Gallium Nitride (GaN) 8-Watt Power Amplifier Modules (PAM) QPA3908 and QPA3810 that combine high performance and are significantly smaller than traditional discretes Component solution footprint advantages, thereby reducing the board-level footprint required by network infrastructure equipment manufacturers. Target applications for both products include massive MIMO base stations for active antenna systems and O-RAN networks.
The PA3908 and QPA3810 are integrated two-stage PAMs designed for Massive MIMO applications with a device output of 8 watts RMS. The QPA3908 operates from 3.7–3.98 GHz. The QPA3810 operates from 3.4–3.8 GHz. Both modules are matched to 50 Ω input/output, requiring few external components.
Nippon Electric Corporation (NEC) has a long tradition of pursuing technological innovation and collaborating with leading industry suppliers. NEC has partnered with Qorvo to implement the QPA3908 and QPA3810 PAMs to deliver state-of-the-art 5G end-to-end O-RAN networks.
Diwakar Vishakhadatta, general manager of Qorvo's Infrastructure Business Unit, said: "Qorvo's 5G GaN solutions can reduce cost and increase capacity, enable higher levels of integration at the board level, and reduce complexity. We are committed to providing customer partners with Improve efficiency and linearity.”
Both the QPA3908 and QPA3810 contain a driver PA and Doherty final stage to provide high power added efficiency for the entire module at 8W average power. Modules are input and output matched components for superior performance and are fully assembled with no additional tuning required. These single-tuned modules simplify 5G network architecture and reduce design time, providing a better solution than multiple discrete PAs.
