• Sub 6 GHz 5G bands will have 5,10, 20, 25, 30, 40, 50, 60, 80,100 MHz channel bandwidths

• Bands N1, 2, 5, 7, 8, 20, 28 (all FDD), F38, 51 (TDD), F71, 74 (FDD), and F76, 81-84 have channel BW of 20 MHz or less, like 4G

5G/mmWave phased arrays drive a paradigm shift in the approaches that can be taken…greater integration is needed

8

• Smallest # of components• Lowest power dissipation• Most sensitive to

interconnect loss• Complexity in phase shifting

• Large # of components• High power dissipation

(except for FDX)• Simple to implement

• For large array where analog & digital beamforming are inefficient and complex

Summary and conclusion

• 5G is on the tactical horizon with deployments being accelerated….significant announcements made bringing 5G closer to reality

• 5G NR spec driving increased complexity in radio hardware to support 5G, and for backwards compatibility without degrading 4G/LTE performance

• This complexity is being compounded by more stringent RF performance requirements

• Significant growth in RF FEM SOI content is anticipated due to the architectural complexities and performance requirements needed to address 4G and 5G NR coexistence

• GF has a rich portfolio of SOI offerings that align well with proposed architectures and continue to advance in order to meet the challenges of 5G NR requirements
