Title: Practicalities of Building a 28 GHz Small Cell

Date: April 16, 2020

Time: 8am PT / 11am ET

Sponsored by: Knowles Precision Devices

Presented by: Tim Brauner, Product Manager, Microwave Products Group, Knowles Precision Devices

Small cells are an increasingly common way to deploy 5G in the mmWave spectrum because they provide increased network capacity, improved network performance, and more reliable coverage. Phased array systems are critical to these 5G small cells, allowing engineers to enter the mmWave spectrum and take advantage of the higher bandwidth and speed 5G offers in a way that is practical and affordable.

During this Webinar, Knowles Precision Devices will discuss the key considerations building a 28 GHz small cell for 5G applications. We’ll review the critical building blocks that serve as the backbone of phased array systems and address the practical considerations for selecting these passive components, including size, tolerance, and thermal concerns. Then, we’ll walk through a 5G small cell reference architecture and discuss the core components that can make or break your system.

We’ll discuss the following topics:

  • Basic requirements for building a 28 GHz small cell system, including size requirements, thermal constraints, efficiency, power, and cost.
  • Selection criteria and options for implementing RF filtering at mmWave frequencies, including newly available options for the 28 GHz band.
  • Considerations around implementing feed arrays, including the use of power dividers inside beam forming network and tradeoffs of power dividers at mmWave frequencies.
