Abstract

This paper presents Power Amplifier solutions for 5G using GaN SiC HEMT technology. The difference in performance between $0.15 \mu \mathrm{m}$ and $0.25 \mu \mathrm{m}$ GaN HEMT devices is discussed. Measurements show $0.25 \mu \mathrm{m}$ GaN HEMTs provide good performance for applications up to 18 GHz, including excellent performance in the Sub-6 GHz 5G bands. $0.15 \mu \mathrm{m}$ GaN HEMTs currently offer good performance for applications to more than 32 GHz, including excellent performance in the 24-28 GHz 5G mm-wave band. Variations on the $0.15 \mu \mathrm{m}$ process are also being developed to extend the operation frequency to cover the US 5G mm-wave band at 39 GHz and operation over 40 GHz to include Q band Satellite. This paper discusses performance of a discrete GaN power transistor (power bar) DC - 14GHz, with high power density and PAE in a single stage transistor that offers strong performance suitable for Sub-6 GHz 5G. It also discusses performance of a 2-stage 5W PA MMIC 24-28 GHz which is ideally suited for mm-wave 5G.
