The space industry is undergoing a transformative shift to “New Space,” driven by the increasing demand for ubiquitous connectivity and the emergence of innovative business models. One of the key elements of this transformation is the adoption of gallium nitride (GaN) technology in space applications. GaN holds immense potential due to its impressive radiation hardness, high system efficiency and lightweight characteristics.

In a discussion with EE Times Europe, Taha Ayari and Aymen Ghorbel, technology and market analysts at Yole Intelligence, part of Yole Group, explained how New Space—the low Earth orbit (LEO) mission segment, with a typical satellite lifespan of three to five years and lower reliability requirements—has become a focal point for GaN adoption. As a result, power GaN devices are being adopted for various satellite systems, including DC/DC converters, point-of-load systems, motor drives and ion thrusters.

2023年7月3日中国商务部宣布8月起对镓、锗相关物项的出口实施管制。宜普电源转换公司的晶圆技术是硅基氮化镓，尽管每个器件中有其微量镓含量，相对全球镓来源广泛，宜普的需求相对较小。我们预计不会出现短期或长期的供应中断。

案例聚焦新一代替代硅技术

(加利福尼亚州，埃尔塞贡多）--氮化镓（GaN）技术的全球领导者宜普电源转换公司（Efficient Power Conversion Corporation, EPC）于今日向美国联邦法院和美国国际贸易委员会（U.S. International Trade Commission, ITC）提起诉讼，主张其基础专利组合中的四项专利受到英诺赛科（珠海）科技有限公司及其子公司（统称英诺赛科）侵犯。 这些专利涵盖了宜普公司独家的增强型氮化镓功率半导体器件的设计和制造工艺的核心环节。这些专利是创新技术，已成功将基于氮化镓的功率器件从一个研究项目，发展成为一个可大批量生产的替代硅产品。使用氮化镓器件的晶体管和集成电路，较使用硅基器件而言更高效，更小型，成本更低。

This panel discussion from Electronica 2022 discusses the benefits and challenges for SiC and GaN in multiple application contexts, as well as the last barriers to overcome for widespread adoption, such as large-volume capabilities and prices.
