Mobile devices—smartphones, phablets, and tablets—are everywhere. From communicating with friends, family and coworkers, to filming videos, to watching movies, to playing games, to managing fitness goals—today’s mobile devices have become essential to everyday life.
Smartphone demand is expected to exceed 1.3 billion units globally in 2020. While overall smartphone sales have remained relatively steady, the demand for more features and reduced latency is significantly driving up the internal content and complexity. Mobile wireless networks have evolved from predominantly voice-centric networks to advanced high-speed networks that deliver voice, video and data, enabling consumers to access bandwidth-intensive, rich media content on mobile devices through applications such as videoconferencing, streaming media and interactive gaming. Due to ever-increasing data consumption demand, mobile devices must be able to support and manage higher bandwidths made possible by fifth generation wireless (5G) transmissions.
Mobile devices have evolved from supporting only a single cellular standard, operating on two or three frequencies and using a single antenna, to supporting multiple wireless protocols and frequency bands, and integrating multiple antennas. As a result of 5G, the growing number of bands and expansion of multiple-input and multiple-output (MIMO) combinations are exponentially increasing the complexity of the radio frequency front end (RFFE). More than 40 different frequency bands are currently used across the globe to support the long-term evolution (LTE) standard, with the FR1 and FR2 frequency band applications for new radio (NR) expected to add to that. This complexity is driving the need for improved performance in the RFFE components—specifically low loss, low noise figure, high linearity, high isolation and high out-of-band attenuation.
Based on our UltraCMOS® technology, our RF solutions are ready for 5G’s complex requirements and can be found in many top-tier smartphones. In addition to being a member of the 3rd Generation Partnership Project (3GPP), pSemi works closely with global operators and industry organizations to identify future challenges and develop cutting-edge RF solutions. Our products are optimized to meet the tight area requirements of smartphone form factors while still delivering best-in-class RF performance.
