RF Technology Roadmap for 5G and 6G RF Front-end Systems

The evolution of 5G and 6G wireless systems adds considerable challenges to new RF front-end designs and their implementation. For 5G FR1 (450 MHz to 6 GHz) and FR2 (20–60 GHz), there is a significant increase in bands with more band combinations and extensions of the spectrum at higher frequencies. Beyond 5G, new FR3 (7–24 GHz), FR4 bands (>90 GHz) allocations are calling for disruptive semiconductor solutions. In this paper, we will provide a roadmap for RF technology including the engineered substrates enabling solving design challenges of wireless communication systems.
