ADI's RF Front-End Family Enables Compact 5G Massive MIMO Network Radios

摘要

Massive multiple input, multiple output (M-MIMO) radios have seen their popularity surge in the late stage deployment of 4G LTE cellular base stations, particularly in dense urban areas where small cells effectively filled the cellular coverage voids while boosting higher data speed services. The success of this architecture clearly proved its worth. It is poised to be the architecture of choice for nascent 5G network radios, as required spectral efficiency and transmission reliability characteristics are inherent to this architecture. The challenge to making 5G a reality is that designers must vastly increase the number of simultaneous transceiver channels operating in multiple bands, while also squeezing all the necessary hardware into a form factor that is as large as or smaller than the previous generation's equipment.
