On January 16, 2018, the MT-2020 (5G) Promotion Group announced the third phase of its 5G technology R&D trials in Beijing. This milestone marked a crucial step toward commercial readiness, with key players in the 5G supply chain expected to reach pre-commercial status by the end of 2018. This progress laid the groundwork for large-scale trials and eventual 5G deployment. As the trials advanced into their third stage, Qorvo, a global leader in RF innovation, continued to support its partners in refining product designs, accelerating the journey toward full 5G commercialization.
Compared to previous generations like 2G, 3G, and 4G, 5G brings three major technological advancements to boost speed and capacity: the use of more frequency bands, MIMO multi-antenna technology, and carrier aggregation. These innovations are essential for meeting the growing demand for faster and more reliable connectivity.
In terms of frequency bands, 5G is set to double the number of supported bands by 2020, adding over 50 new bands. The total number of bands across all networks—2G, 3G, 4G, and 5G—is expected to exceed 91. As the number of frequency bands increases, so does the complexity of filter design. The demand for filters is also expected to grow significantly, potentially reaching several times the current level. In practical applications, modern smartphones already support up to 13 frequency bands, a sharp increase from the four bands used in early 2G devices and nine in 3G models. Each generation of communication technology has brought a substantial rise in the number of supported bands.
MIMO technology plays a vital role in boosting data rates and network capacity. It's a cornerstone of LTE and a critical component for 5G. By 2020, it's anticipated that MIMO 64x8 will become the standard, with base stations using 64 antennas and mobile devices adopting 8. This represents a massive jump from current 2x2 MIMO configurations. The expansion of MIMO requires a significant increase in both base station and device antennas, creating new opportunities for the antenna industry and driving growth in related sectors.
Carrier aggregation further enhances performance by combining multiple narrow bands into one wide channel, leading to higher speeds. However, this also increases the complexity of RF systems and the demands on RF components. As carrier aggregation becomes more widespread, the RF MEMS switch market is expected to grow rapidly. Current SOI-based switches are nearing their technical limits, especially in terms of IIP3 performance. Only RF MEMS switches can meet the high standards required for 5G, positioning them for strong growth in the coming years.
RF devices are already a major market, valued at over $20 billion. With the rising demand from 4G+, 5G, and the Internet of Things, this sector is set for rapid expansion. According to Yole’s 2017 report, the global RF power component market is projected to grow from $1.5 billion in 2016 to $2.5 billion by 2022, with a compound annual growth rate of 9.8%.
As 5G development accelerates, competition among top vendors intensifies, with each striving to lead the next era of wireless technology. Qorvo remains at the forefront, leveraging its expertise in cutting-edge RF solutions. From LowDrift and NoDrift filtering technologies to RF Fusion and RF Flex front-end solutions, and even GaN-based components, Qorvo offers industry-leading products. The company continues to collaborate with operators and standards organizations to bring 5G visions to life, ensuring it stays ahead in the evolving landscape.
