Semiconductors and Mobile Communications: 5G and Beyond

Semiconductors and Mobile Communications: 5G and Beyond
by Kalar Rajendiran on 03-06-2023 at 6:00 am

Mobile World Congress (MWC) is the world’s largest gathering of mobile industry innovators where one can hear the latest on advanced technologies and solutions. This year, it took place from February 27 through March 2. Soitec was there to share their insights on how mobile communications are going to evolve with 5G and beyond and showcase their innovative solutions. The company highlighted the critical role semiconductors will play to deliver on the full promise of 5G and beyond and corresponding silicon opportunities. It also demonstrated its commitment to sustainability by showcasing a number of initiatives it has implemented to reduce its environmental footprint.

5G Transforming the World

As the technology world continues to advance, 5G is quickly transforming the way we think, work, and interact. 5G is creating a new era of connectivity and enabling us to experience faster, more reliable networks and data speeds. It has significantly increased the demand for reliable, high-performance RF Front End (RFFE) solutions.

RF at the Heart of 5G Mobile

RFFE circuitry is what processes the radio frequency signals in a mobile device. It is responsible for transmission and reception of signals, amplification of signals, and noise reduction. In other words, it is the heart of mobile communications and is essential for providing seamless connectivity. With every new generation of mobile connectivity, the demand for higher speeds, wider bandwidths and better performance has been increasing. 5G will be the key engine powering our connected society through the end of this decade, in a wide range of markets. Public and private 5G networks, fixed wireless access (FWA), smart transportation, non-terrestrial networks, massive IoT, and XR (VR/AR/MR) are markets to name a few. The RFFE circuitry has increased in complexity over the generations and will continue to increase in complexity as 3GPP’s new releases for 5G are announced. The main challenges for 5G RFFE for mobiles are high-speed communications, long battery life and circuity footprint optimization.

Soitec’s Unique Position

Soitec’s RF-SOI has already become a standard for implementing front-end modules in smartphones. Its RF-SOI, FD-SOI, Piezo-on-insulator (POI) and Gallium Nitride (GaN) technologies are specifically designed to address the challenges of 5G RFFE.

RF SOI Substrate Standard for 4G and 5G

Together, the RF-SOI and FD-SOI solutions will enable high-performance 5G RFFE at reduced power consumption and lowest cost. The POI technology from Soitec enables implementation of high-performance 5G filters to support a wide range of upcoming 5G applications in the sub-6GHz spectrum. The GaN technology is designed to enable extremely high-speed and low-power solutions for 5G RFFE.

The following chart highlights the semiconductor opportunity for Soitec’s above mentioned technologies in high-end smartphones over the next four years.
