Title: New Opportunities for SOI Technology in 5G Massive MIMO Base Stations

Date: May 26, 2022

Time: 8am PT / 11am ET

Sponsored by: pSemi

Presented by: Payman Shanjani, Technical Director, RFIC Design

As more 5G massive MIMO base stations replace remote radio units (RRU), it creates new opportunities to leverage silicon-on-insulator (SOI) technology to reduce cost and power consumption while improving performance and integrability. Unlike traditional base stations that require high-breakdown voltage technologies, massive MIMO structures utilize many RF lines with lower power transmitters and higher isolation requirements. This transition makes SOI the most suitable solution for both sub-6 GHz and mmWave active antenna systems (AAS).

This webinar will discuss:

  • Benefits and challenges of massive MIMO versus traditional RRU base stations.
  • System and specification requirements of RF building blocks.
  • Opportunities for utilizing SOI technology in RF components.
  • How to leverage SOI to realize hybrid beamforming and phase-shifting topologies.
  • Practical examples of existing SOI-based RF components utilized in AAS.
