5G network infrastructure demands reliability and performance across a wide range of subscriber, environmental, and regulatory conditions.

Longevity and adaptability of supply and technology are also key to the success of telecommunication infrastructure networks, including cellular, microwave, mmwave and optical backhaul, and mobile radio networks. IQE has evolved and delivered epiwafer and substrate products enabling wireless and optical communications over all of the telecommunications network infrastructure generations fielded.

IQE is investing in new epitaxial and substrate technologies to support high-speed connectivity for increasingly data intensive and rapidly emerging 5G applications. Our gallium nitride (GaN) technology for RF massive MIMO (multiple-input, multiple-output) is in volume production providing our customers with a significant competitive advantage with our custom engineered GaN epi on silicon or silicon carbide (SiC) substrates.

The matrix below demonstrates how IQE’s broad range of wireless and photonic epitaxial wafer products address applications across the 5G network infrastructure market.
