Application of Technology in Communication

Compared with silicon semiconductors, compound semiconductors have excellent performance such as high frequency and high power, and are irreplaceable core technologies for future 5G communications. The Chinese market is a large mobile communications market, and 5G communications will soon be commercially available. It is expected to rely on new market opportunities to enhance the competitiveness of the compound semiconductor industry. The development of domestic compound semiconductors and 5G communication chips is facing a rare window period, with both opportunities and challenges.

In order to better promote industry exchanges and provide a platform for domestic outstanding compound semiconductor and 5G communication chip companies to connect resources with local governments, investment companies, and technical experts, the China Electronics Information Industry Development Research Institute will promote China's integrated circuit industry in 2018 During the conference, the 5G communication chip theme forum was organized and invited many national investment institutions, upstream and downstream enterprises and technical experts including Qorvo, discuss the development path of my country's 5G communication chips from multiple levels such as policy, investment, technology, and industry?

China Electronics Information Industry Development Research Institute will organize the 2018 China Integrated Circuit Industry Promotion Conference (China Chip Conference) at Nanping International Convention and Exhibition Center on November 9. The conference has been held for 12 consecutive sessions. It is one of the influential and authoritative industry conferences in the domestic integrated circuit field. It is a major review and vane for domestic integrated circuit product innovation and application innovation. This session to "core era, core as" as the theme, around the establishment of "China core" new corporate image exchanges.

Compound Semiconductor & 5G Communication Related Guide

5G smartphones will make extensive use of GaAs RF devices. With the continuous improvement of mobile communication frequency, Si devices can no longer meet the performance requirements, and the power amplifiers in 4G smart phones have all adopted GaAs technology. The number of communication bands supported by 5G communications will increase significantly to more than 50, much larger than the number of bands (no more than 20) for 4G communications. In order to ensure the quality of communication, it is necessary to increase the number of amplifiers or improve the integration of devices. Sadie think tank predicts that the GaAs device market will reach 10 billion billion US dollars in 2020.

5G communication base stations are in urgent need of higher performance GaN RF devices. GaN RF power amplifiers combine the high power of Si devices with the high frequency characteristics of GaAs devices. In order to cope with the problem of low efficiency of Si devices in the frequency band above 2.4 GHz, 4G communication base stations begin to use GaN power amplifiers. Currently, about 10% of base stations use GaN technology. About 1.5 million new base stations are built each year around the world, and future 5G networks will complement smaller and more densely distributed micro-base stations. Sadie think tank expects the GaN RF device market to exceed $0.6 billion in 2020.

Developed countries have completed the strategic layout of compound semiconductors. At the beginning of the 21st century, the United States and Europe began to organize technical and industrial support projects, cultivated a number of leading enterprises, and occupied the highlands of technology and market. DARPA of the U.S. Department of Defense has released the Wide Band Gap Compound Semiconductor Technology Innovation Program (WBGSTI) and the Next Generation GaN Electronic Device Program (NEXT) since 2002, helping Qorvo and other compound semiconductor companies to rapidly grow into industry leaders.

In terms of manufacturing maturity, Qorvo has shipped more than 2.6 million GaN device products since 2008, 170000 of which are used in the radar field. Qorvo's GaN products have reached the U. S. Department of Defense Manufacturing Maturity Assessment (MRL) Level 9.
