In this technical paper, we analyze the architecture, semiconductor technology, and RF front-end (RFFE) design needed to deliver mmWave FWA services. Discussing topics such as: Scan-angle requirements, Tradeoffs of Hybrid-beamforming versus All-Digital Beamforming for the Base Transceiver Station (BTS),Analyze BTS semiconductor technology and RF front-end components, and Gallium-Nitride on Silicon Carbide (GaN-on-SiC) front-end modules (FEMs) designed specifically for the 5G FWA
