Global smartphone shipments fluctuate around 1.2 billion units annually, driving a dozen-billion-dollar RFFE market. With the evolution of communication standards and RFFE architectures, market vitality will further intensify. The gradual introduction of 5G-A/6G standards and in-depth development of spectrum resources have brought more complex system requirements, including demands for MIMO UL/DL support, increasing CA combinations, and more coexistence scenarios to manage. The activation of non-terrestrial networking and topology expansion will also perfect the integrated air-space-terrestrial wireless communication network. Once RFFE devices iterate to meet these challenges, we can almost stay connected worldwide from anywhere on Earth via a simple smartphone in hand.
Compound semiconductors play a key role in addressing these challenges. GaAs PA modules remain the core of RFFE systems, while LT SAW filters have become increasingly critical due to higher demand in modules and technological advancements.
