New pSemi Sub-6 GHz RF Switches that Enable Hybrid Architectures in 5G Massive MIMO Base Stations

pSemi Corporation, a Murata company focused on semiconductor integration, expands its portfolio of RF SOI switches targeted for the latest 5G wireless infrastructure and massive MIMO base station deployments. By using the new high linearity switches in hybrid architecture topologies, base station designers can save valuable board space and improve thermal management, reducing the overall system’s cost, weight, and power consumption. pSemi’s advanced SP4T switches deliver best-in-class linearity, insertion loss, and power handling performance to improve spectral efficiency in sub-6 GHz active antenna systems.

5G base stations covering sub-6 GHz offer network providers an immediate path to wider bandwidths and increased data throughput. New 3 to 5 GHz allocations and added antenna design complexities create the need for new hybrid beamforming and phase-shifting topologies. Massive MIMO systems use hybrid architectures to minimize power-hungry digital processing and reduce the number of power amplifier components. These hybrid architectures offer the ideal balance of digital and analog, combining the flexibility of digital beamforming with the power efficiency and design simplicity at the analog RF front end (RFFE).

Vikas Choudhary, VP of sales and marketing at pSemi said, “Active antenna systems are driving a drastic increase in demand for RFFE components, along with tougher FR1 switching requirements for advanced 5G networks. As the industry leader in RF and mmWave switching, pSemi continues to push the boundaries of SOI technology and design RFIC solutions that empower base station OEMs and support the demands of 5G and beyond.”

Each UltraCMOS PE42443 and PE42444 switch delivers industry-leading RF performance across the n41, n77, n78, and n79 bands. These operate from 1.8 to 5 GHz. These pSemi SP4T switches consist of selectable phase shifts that enable analog beam control features utilized in hybrid beamforming architectures. They are available in 4 x 4 mm LGA packages.

Key features and benefits of these switches:

  • Spectral efficiency — High linearity and high power handling maximize data throughput.
  • Energy conservation — Low insertion loss improves overall system efficiency.
  • Flexible beam management — Fast switching speed supports symbol-level analog beam adjustments to enable massive MIMO systems.
