The database is calibrated with the input of chip size, ASP of both device and wafer, and market trends.
By calibrating the ramp-up of 800V EV and SiC penetration in the forecast period, along with adjustment of SiC penetration in different applications, such as telecom power supply and rail traction, the forecast of 2021-2027 is available in this quarter.
- GaN power
We updated our end-systems database, and GaN adoption rate in consumer, telecom and industrial applications. The forecast of 2021-2027 is available in this quarter.
- SiC power
- Module II:
- RF GaN
The forecast of 2027 is implemented, by reviewing the latest trends in relevant market, for example the base-station deployment in telecom applications.
In this quarter, we updated the key parameters. Chip size of PA used in the systems us adjusted by aligning the latest teardown reports from System Plus Consulting. Telecom as one of the major market for RF GaN, the database of end systems has been calibrated with industrial feedback to reflect the global slowdown of deployment and regional difference.
Meanwhile, the adoption of RF GaN technology for different OEMs is taken into consideration. In this context, the penetration of RF GaN has been calibrated to reflect the market dynamics in the forecast period to 2027.

SiC and GaN compound semiconductors have become key segments in the power semiconductor industry
SiC and GaN are continuing their rapid market evolution from 2018-2019, but now have different drivers behind their growth. After Tesla’s adoption of SiC in its inverters, another trend is reshaping the electric vehicle (EV) market, namely fast 800V EV charging allowing shorter charging stops. SiC is the enabler, with promising performance and a growing supply chain. As of 2022, we’ve seen high-volume EVs including BYD’s Han and Hyundai’s Ioniq5 using SiC. Top device players, such as STMicroelectronics, Infineon, Wolfspeed, onsemi and ROHM, delivered record revenue in 2021. They will each move forward to $1B SiC revenue in the 2023-2025 timeframe. Apart from automotive, now industrial, energy and rail applications provide extra momentum to grow. The capacity build-up, business integration and new business models will bring SiC to another level in years to come.
Meanwhile, GaN continues entering consumer applications, mainly fast chargers for smartphones. Power Integrations and Navitas are leading the market with multiple design-wins with phone makers. Innoscience also announced shipments exceeding 30M devices by 2021. Recently, Navitas and GaN Systems announced shipping to Samsung for GaN-based 45W accessory mobile fast chargers. In Q1-22, Navitas have achieved two design wins for in-box chargers. In Q4-21, Apple adopted GaN in the MacBook pro charger for the first time, featuring GaN Systems’ devices. In the long term, telecom and datacom applications will need high efficiency power conversion to meet CO2 emission objectives. The on-board chargers and DC-DC converters in EVs are opportunities for GaN to grow to a $2B business in 2027. Several players like EPC, Transphorm and Texas Instruments already have automotive-qualified products and are actively working on designs for EV.
A different story for GaN and SiC in RF applications
For many years, RF GaN has been used to build 4G base stations because of its outstanding performance in the power amplifier stage. Meanwhile, defense applications consistently stretch the demand for RF GaN in military radar and electronic warfare systems. However, with the US ban on Huawei, Covid’s impact and slowdown of base station deployment, RF GaN faced an adjustment period in 2021. That directly influences the market in 2022. For example, we show the change of growth rate in our forecast for semi-insulating SiC wafer shipments. As base station deployment recovers and penetration of RF GaN in high-frequency, beam-forming systems increases in the years to come, we will keep tracking the latest movement at each level of supply chain.
