BARCELONA -- Qorvo (Nasdaq:QRVO), a leading provider of innovative RF solutions that connect the world, today announced two highly-integrated dual channel switch-LNA modules for base station implementations of massive multiple-input/multiple-output (MIMO). When combined with Qorvo’s GaN-based integrated driver and power amplifier module, the dual channel switch-LNA modules provide a complete, highly integrated solution for wireless infrastructure manufacturers seeking to quickly and cost-effectively implement pre-5G massive MIMO networks.

Mobile operators are increasing data capacity with the deployment of sub-6 GHz massive MIMO networks. Strategy Analytics predicts that 5G networks using massive MIMO will be operational by 2020 and that there will be approximately 700 million 5G connections by 2025. Massive MIMO allows base stations to transmit multiple streams of data, while beamforming will bring higher gain and power, allowing for greater data capacity.

James Klein, President of Infrastructure and Defense at Qorvo, said, “Qorvo is uniquely positioned to deliver complete system solutions that leverage our broad portfolio of highly differentiated products and internally developed technologies. With today’s product announcement, we expand our portfolio of receive and transmit front-end modules for additional frequency bands targeted at pre-5G and 5G wireless infrastructure, in anticipation of more spectrum being made available below 6 GHz.”

Qorvo's QPB9318 and QPB9319 are highly integrated dual channel switch-LNA modules that support frequency bands below 5GHz. The dual channel switch-LNA modules pair with Qorvo’s high performance GaN-based QPA2705 to provide a complete massive MIMO RF solution. At IMS 2016, Qorvo demonstrated industry-leading ultra-wideband linearization results with the QPA2705.

With Qorvo’s complete solution, operators are able to implement highly efficient, small form-factor massive MIMO transceivers for next-generation base stations. The QPB9318 and QPA2705 are currently shipping in production volumes to large base station OEMs, and samples of the QPB9319 will be available in the June quarter.
