GaN on SiC – A Key Technology for 5G Cellular Power Amplifiers

Monday, May 10, 2021

The power amplifier (PA) has many challenges in 5th generation cellular infrastructure transceivers at sub-6 GHz TDD frequency bands. It should be able to transmit multi-carrier and multi-mode signals that occupy the full frequency span of a given communication spectrum, while also meeting challenging power, efficiency, and linearity requirements. The demand on the PAs increases significantly in terms of power-added efficiency and bandwidth compared to previous generation systems and makes GaN on Silicon Carbide (SiC) the ideal technology choice for the PA.

Attendees will learn:

  • Why we need new spectrum for 5G <6 GHz applications
  • Requirements and challenges for 5G power amplifiers
  • Benefits of GaN for cellular power amplifier designs
  • How Wolfspeed enables 5G with a vertically integrated GaN front-end
