TL;DR · WeSearch summary

Gallium arsenide has long been the standard material for high‑frequency radio‑frequency (RF) devices, but the industry is increasingly adopting gallium nitride (GaN) for its superior performance at higher frequencies, power levels, and temperatures. The transition to GaN is complicated by the need for new metrology techniques to ensure reliability, scalability, and commercial competitiveness. Additionally, GaN’s distinct manufacturing processes require a whole‑system redesign rather than a simple material substitution.

Key facts

▪GaAs has been the mature, cost‑effective choice for RF devices used in satellite communications, radar, and mobile networks.
▪GaN enables devices to operate at higher voltages, temperatures, and power densities, making it attractive for 5G/6G, defense, and space applications.
▪Accurate measurement and metrology are critical to overcoming reliability and scalability challenges associated with GaN technology.
▪GaN’s manufacturing approach differs fundamentally from GaAs, necessitating a comprehensive redesign of modules rather than a direct material swap.
