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).
“Active antenna systems are driving a drastic increase in demand for RFFE components, along with tougher FR1 switching requirements for advanced 5G networks,” says Vikas Choudhary, vice president of sales and marketing at pSemi. “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.”
