Top Three Challenges with DPD Linearization for 5G MIMO Transmitters

In this webinar, we shall discuss wireless infrastructure; where we are now and where we’re heading. We’ll detail some challenges with DPD linearization that 5G will bring: bandwidth, massive MIMO, and TDD operation. Also, we shall describe how the industry needs some DPD development to meet the linearity (and other performance) specifications, as well as how partnerships between industry sectors will make 5G a success.

Attendees will learn:

Digital Pre-Distortion approaches for 5G
Linearization Challenges in 5G: bandwidth, massive MIMO, TDD operation
GaN power HEMT capabilities for 5G
