Application Insights

The global RF GaN (Radio-frequency Gallium Nitride) market is bifurcated into military, telecom infrastructure (backhaul, RRH, massive MIMO, small cells), wired broadband, satellite communication, commercial radar and avionics, RF energy, and other applications. The military dominated the market and is estimated to register a CAGR of 22.7% during the forecast period. The modernization of defense equipment is increasing the need for high-power semiconductor devices. Also, the growing demand for high-power applications is increasing the need for high frequencies in the defense sector. This provides several growth opportunities for the market. Defense applications are increasingly using RF GaN power devices due to the need to replace old vacuum tube designs with solid-state technologies that deliver the requirement for higher frequencies. The need for the RF power market is also driven by the growing use of GaN as the basis for devices that give radar and electronic warfare systems ECM (electrochemical machining) capabilities, particularly for land-based RF jammers to protect troops. The military uses the RF GAN as an alternative or replacement for laterally diffused MOSFET (LDMOS) components in military radar and EW system designs. Over the anticipated term, this is anticipated to accelerate market expansion.

The telecom infrastructure segment is the second largest. Furthermore, the 5G technology is expected to revolutionize the domain of various broadband services and empower connectivity across different end-user verticals. The main drivers responsible for increasing the market share are increased mobile subscriptions, online video content streaming, strengthening 5G infrastructure, and various IoT applications utilizing 5G. 5G is anticipated to support various services and associated service requirements across multiple scenarios. With 5G, the density of RF solutions required increased exponentially. That makes it imperative to reduce energy consumption. GaN power transistors have become a key component of base station technology for 5G, providing the finest performance. To increase electron entrapment in the semiconductor, NXP improved their GaN technology, primarily to guarantee strong linearity and low memory effects. Similar investments and expansions are anticipated to accelerate the market under study's growth.

The number of 5G mobile subscriptions was valued at 0.42 million in 2019, globally, and it is expected to reach 400 million subscriptions by 2022. With the substantial growth in the rollouts of 5G technology globally, the demand for RF GaN technology is expected to increase.

Material Type Insights

The global RF GaN (Radio-frequency Gallium Nitride) market is segmented into GaN-on-Si, GaN-on-SiC, and other material types (GaN-on-GaN, GaN-on-Diamond). The GaN-on-Si segment dominated the market and is estimated to register a CAGR of 17.6% during the forecast period. Some major applications of GaN-on-Si devices include base stations and telecommunication, defense and aerospace, and satellite communication, among others. Besides, these devices are widely implemented in LEDs and power electronics. Traditionally, base stations have been using laterally-diffused metal-oxide-semiconductor (LDMOS) (planar double-diffused MOSFET technology) based RF power amplifiers (PAs) devices. However, over the past few years, RF GaN devices have displaced LDMOS devices in base stations. While LDMOS still represents a significant share of base station power amplifiers revenue, the GaN is expected to have a higher growth rate and become more prevalent as 5G deployments go higher in frequency. While the GaN-on-Si within 150mm wafer diameter is already being deployed for various end-use applications, 200 mm diameter, GaN-on-Si wafers are in the process of development by leading players in the manufacturing space. Such key trends are anticipated to drive the market's growth during the forecast period steadily.

Regional Analysis

Asia-Pacific dominated the market and is estimated to register a CAGR of 19.3% during the forecast period. China, Japan, Taiwan, and South Korea account for around 65% of the global market for discrete semiconductors. Other countries like Thailand, Vietnam, Malaysia, and Singapore also significantly contribute to the Asia-Pacific area's market supremacy. In military applications, due to the increase of T/R systems in airborne radar, GaN devices are replacing bulky traveling wave-tube (TWT)-based systems, ensuring that defense will remain among the primary drivers of the GaN market. According to the Stockholm International Peace Research Institute (SIPRI), China and India were the second-and third-largest military spenders in the world in 2019. China's military expenditure reached USD 261 billion in 2019, a 5.1% increase from 2018, while India's expenditure grew by 6.8% to USD 71.1 billion. Such instances are likely to boost the market growth in the region.
