The RF GaN industry is showing an impressive growth with a 23% CAGR between 2017 and 2023, driven by telecom and defense applications. By the end of 2017, the total RF GaN market was close to US$380 million and 2023 should reach more than US$1.3 billion with an evolving industrial landscape (1). Telecom and defense are looking for innovative technologies and RF GaN-based devices are directly answering to the market demand.

Defense remains a major RF GaN market segment, as its specialized high-performance requirements and low price sensitivity offer many opportunities for GaN-based products. In 2017-2018, the defense sector accounts for more than 35% of the total GaN RF market, and the global defense market shows no signs of slowing down (1).

“We believe this important GaN market segment will continue growing along with GaN’s overall penetration rate,” asserts Hong Lin, PhD. Senior Technology & Market Analyst at Yole Développement (Yole), part of Yole Group of Companies.

Under this dynamic ecosystem, Yole’s partner, Knowmade, has deeply analyzed the RF GaN IP landscape and proposes today a dedicated report, RF GaN 2019 – patent landscape analysis. This report reveals the competitive landscape from a patent perspective. Key patent owners, IP & technology strategies, and future intents have been deeply analyzed by Knowmade’s analysts. This report details competitors’ strengths and weaknesses in terms of patents and technologies. It also proposes a comprehensive description of the technology trends and emerging technologies status.
GaN RF has been recognized by industrial companies and has clearly become mainstream. Leading players are increasing revenue very rapidly and this trend will remain for the next several years. From an IP perspective, American and Japanese players dominate the RF GaN IP ecosystem. So who are the leading RF GaN companies? What is the status of their patent portfolio? Do they have the right IP portfolios to face huge opportunities?…

Knowmade’s analysts invite you to discover the status of the RF GaN IP landscape.

“Cree (Wolfspeed) indisputably has the strongest IP position, especially for GaN HEMTs on SiC substrate,”comments Nicolas Baron, PhD., CEO and co-founder of Knowmade. “Sumitomo Electric, the market leader in RF GaN devices, is well positioned but far behind Cree.”

Furthermore, Sumitomo Electric has been slowing down its patenting activity while other Japanese companies like Fujitsu, Toshiba and Mitsubishi Electric are increasing their patent filings and thus today have strong patent portfolios as well.

Intel and MACOM are currently the most active patent applicants for RF GaN, both especially for GaN-on-Silicon technology, and are today the main IP challengers in the RF GaN patent landscape.
Other companies involved in RF GaN market, such as Qorvo, Raytheon, Northrop Grumman, NXP/Freescale, and Infineon, hold some key patents but do not necessarily have a strong IP position. CETC and Xidian University dominate the Chinese patent landscape with patents on GaN RF technologies targeting microwave and mm-wave applications. And the emerging foundry HiWafer, entered the IP landscape three years ago, is today the most serious Chinese IP challenger… American and Japanese companies are playing a key role on the RF GaN IP playground.

From a device perspective, Cree (Wolfspeed) has also taken the lead in the GaN HEMT IP race for RF applications… “The analysis of Cree’s RF GaN patent portfolio shows it can effectively limit patenting activity in the field and control the freedom-to-operate of other firms in most key countries,” explains Nicolas Baron from Knowmade.

Intel, which entered the GaN HEMT patent landscape later, is currently the most active patent applicant and it should strengthen its IP position in coming years, especially for GaN-on-Silicon technology. New entrants in the GaN RF HEMT related patent landscape are mainly Chinese players: HiWafer, Sanan IC and Beijing Huajin Chuangwei Electronics.
Other noticeable new entrants are Taiwan’s TSMC and Wavetek Microelectronics, Korea’s Wavice and Gigalane, Japan’s Advantest, and America’s MACOM and ON Semiconductor…

Under this new IP report, the technology intelligence and IP strategy consulting company, Knowmade, has selected and analyzed more than 3,750 patents published worldwide up to October 2018. These patents pertain to RF GaN epiwafers including GaN-on-SiC and GaN-on-Silicon, RF semiconductor devices, including HEMTs and HBTs , integrated circuits, including RFICs and MMICs , operating methods and packaging, for all functions, such as RF PAs , RF switches and RF filters and from radio frequencies <6GHz to microwaves >6GHz and mm-waves >20GHz. A detailed description of this IP report is available on Knowmade’s website.
