Communications Infrastructure

Connecting you to the future with Wolfspeed gallium nitride (GaN) on Silicon Carbide (SiC) technology solutions and industry leading support.

Tomorrow’s 5G demands today’s Wolfspeed GaN on SiC semiconductors.

Telecommunications infrastructure is continually evolving to meet the insatiable demand for a better mobile experience, driving countless cellular base station designs. This demand is encouraging network providers to source reliable and flexible solutions that help them meet these varying requirements.

Wolfspeed is a vertically integrated manufacturer that is expanding our SiC capacity to meet future demands. Our complete portfolio of products is engineered to support all cellular standards and frequency bands to help expand existing 4G system capability and to enable the next generation of 5G networks with state of the art GaN on SiC and LDMOS solutions.

Each day presents a greater need for connectivity across platforms, systems and applications, and 5G is poised to save the day. Successfully enabling a 5G-capable world requires increasingly advanced electronic components running cooler and faster, in smaller, lighter configurations that deliver bulletproof reliability and unprecedented energy efficiency. This is the need which motivates us, and GaN on SiC is our solution.


5G Demands

5G will transmit more data at faster speeds and with greater precision than ever – but only if the network infrastructure can reliably handle unprecedented throughput and backhaul. With 206+ billion field hours of GaN on SiC devices behind us we’ve got a proven ability to get your 5G deployment right the first time.

Unlock the future with GaN on SiC

The promise of unprecedented data speed, low latency and bandwidth that’s an order of magnitude wider has the world clamoring for 5G. RF designers are finding those required gains can best be realized with GaN on SiC components. To achieve the higher linearization, greater power density and improved thermal conductivity required for full 5G capability requires performance improvement at the system level. Already the most capable semiconductor devices in the industry, Wolfspeed’s pioneering GaN on SiC components are offering improved efficiency and bandwidth, and as 5G continues to expand and mature we will continue to expand and explore the advantages inherent in wide bandgap GaN on SiC for system developers seeking better performance everywhere.

The GaN on SiC Solution

Higher throughput requires more bandwidth, which in turn drives the need for more spectrum availability to ultimately reach the potential of 5G technologies. Newer high frequency bands are being made available that will benefit from the capabilities of GaN on SiC. The GaN on SiC combination of high power density, high efficiency, and wide bandwidth makes it the optimal solution for 5G. The GaN on SiC solution offers the faster switching speed and low latency needed for efficient spatial multiplexing, otherwise known as Massive MIMO (multiple in, multiple out), creating much broader bandwidth over an increasing density of small cells and base stations. It’s a connectivity backbone with a nervous system energized by GaN on SiC. Explore the science.
