Wireless Communications Explosion: The Unstoppable Growth Engine

The report identifies the relentless global deployment of 5G infrastructure and the increasing complexity of mobile handsets as the paramount driver for GaAs wafer demand. With the radio frequency (RF) segment accounting for the largest share of the total market application, the correlation between connectivity demand and GaAs consumption is direct and substantial. The market for RF components leveraging GaAs is enormous and continues to expand with the digitalization of the global economy. The demand for high-performance semiconductors capable of handling these frequencies efficiently is insatiable.

"The massive concentration of compound semiconductor device manufacturers and end-users in the Asia-Pacific region, which alone commands the largest global market share, is a key factor in the market's dynamism," the report states. With the ongoing rollout of 5G networks, which heavily utilize GaAs power amplifiers and switches, the pressure on wafer suppliers for high-volume, high-quality production is immense. This is especially true as network architectures evolve to include massive MIMO and millimeter-wave technologies, pushing the performance envelope of semiconductor materials.
