Over the years, we have moved from simple text messages to live video transmission over our smartphones. Tomorrow with 5G, increased data speed will allow also vehicle to vehicle communication, virtual reality, smart home and more.

The front-end module plays a key role in reaching these performance levels.

Carrying your data at very high frequency

Smartphones are integrating very diverse functions including radio emission and reception, digital processing, memory, audio, battery management, camera and display.
The front-end module enables RF signal transmission and reception between a cellular phone and a base station.

Each generation requires more devices and higher performance in the front-end module.
Because RF-SOI can bring better linearity and insertion loss at the best cost/performance trade-off, it enables higher data speeds, longer battery life and fewer dropped calls.

Our RF-SOI products have become a standard of the industry.

They are produced in high-volume manufacturing to manufacture ICs for RF front-end modules while matching chip makers’ cost and performance requirements.

Our substrates enable high RF performance on silicon films compatible with standard CMOS processes, high linearity RF isolation and power signals, low RF loss, digital processing and power management integration.

Our product roadmap addresses the full spectrum of different performance requirements.
