RF GaN growing at 23 percent CAGR
New report ranks main RF GaN players according to number of patent familes they own
The RF GaN industry is showing an impressive growth with a 23 percent CAGR between 2017 and 2023, driven by telecom and defence applications. By the end of 2017, the total RF GaN market was close to $380 million and 2023 should reach more than $1.3 billion with an evolving industrial landscape. Telecom and defence are looking for innovative technologies and RF GaN-based devices are directly answering to the market demand.
Defence remains a major RF GaN market segment, as its specialised high-performance requirements and low price sensitivity offer many opportunities for GaN-based products. In 2017-2018, the defence sector accounts for more than 35 percent of the total GaN RF market, and the global defence market shows no signs of slowing down.
“We believe this important GaN market segment will continue growing along with GaN’s overall penetration rate,” says Hong Lin, senior technology and market analyst at Yole Développement (Yole), part of Yole Group of Companies.
Yole’s partner, Knowmade, has recently looked at more than 3,750 patents published worldwide up to October 2018 and produced a report based on its analysis. The patents apply 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.
“Cree (Wolfspeed) indisputably has the strongest IP position, especially for GaN HEMTs on SiC substrate,” says Nicolas Baron, 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.
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 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.
