2 Solid State Power Amplifiers (SSPA) Market Growth Drivers and Restraints
Continued growth in demand in the military and communications fields
The demand for SSPA in the military field mainly stems from the continuous upgrading of radar systems, electronic warfare equipment and satellite communications. For example, the popularization of active phased array radars requires a large number of high-performance SSPAs to improve signal strength and anti-interference capabilities.
Document data shows that military applications accounted for 46.83% of SSPA market revenue in 2023, the largest application area, and are expected to remain dominant by 2028. In the field of communications, the construction of 5G networks and the development of satellite Internet (such as the Starlink project) have driven the demand for high-power, high-efficiency SSPAs for base station signal amplification and satellite ground station equipment.
Advances in semiconductor technology
The development of third-generation semiconductor materials represented by gallium nitride (GaN) and gallium arsenide (GaAs) has significantly improved the performance of SSPA. GaN technology has high breakdown voltage, high electron mobility and good thermal management capabilities, which greatly improves the output power and efficiency of SSPA in high-frequency bands (such as Ka band) while significantly reducing volume and weight. For example, Qorvo’s Spatium® technology achieves wide-bandwidth, high-reliability power synthesis through GaN power devices, which promotes the development of satellite communications and radar applications.
Increased number of satellite launches and expansion of the aerospace industry
The rise of global commercial aerospace, such as satellite constellation deployment by SpaceX, Blue Origin and other companies, has driven the demand for SSPA. Satellite communications require a large number of high-power amplifiers to ensure signal coverage and transmission quality, especially in Ku and Ka band applications. The document mentioned that the market revenue of Ka-band SSPA increased from US$577 million in 2018 to US$805 million in 2023, with a compound annual growth rate of approximately 6.9%, and is expected to reach US$1.233 billion by 2028.
Driven by critical infrastructure and government applications
The demand for SSPA in government and critical infrastructure fields (such as weather radar, air traffic control, and port security) has grown steadily. For example, weather radar systems require highly reliable SSPAs to achieve accurate weather monitoring and early warning, and radar modernization and upgrade plans in government projects have further driven market demand. In 2023, critical infrastructure and government applications accounted for 8.69% and 14.49% of market revenue, respectively.
Technical Challenges and Design Complexity
In high frequency bands (such as Q/V bands), SSPA faces the problem of lower power output and efficiency than vacuum electronic devices (such as traveling wave tube amplifiers TWTA), and the design complexity is high, requiring complex heat dissipation and power synthesis technology. For example, above the Ka band, the efficiency of SSPA is generally lower than that of TWTA, which limits its application in some high-power scenarios. In addition, the design of broadband matching networks relies on experience debugging and lacks standardized processes, resulting in long R&D cycles and high costs.
Raw Materials and Supply Chain Risks
The supply of SSPA’s core raw materials such as GaN and GaAs wafers is highly concentrated, mainly relying on a few suppliers in the United States, Japan, and Europe (such as Infineon and STMicroelectronics). The fragility of the supply chain may lead to fluctuations in raw material prices and delivery delays, especially in the context of global trade frictions or geopolitical tensions. For example, the Russian-Ukrainian conflict in 2022 led to the disruption of some European semiconductor raw material supply chains, affecting the production of companies that rely on imports.
Pressure from competitive substitutes
TWTA still has power and efficiency advantages over traveling wave tube amplifiers in high frequency bands (such as above Ka band), and has a mature application foundation in fields such as satellite communications. Although SSPA has advantages in reliability and volume, the irreplaceability of TWTA in specific scenarios still creates competitive pressure on the SSPA market. In addition, the high current consumption and heat dissipation requirements of solid-state power amplifiers lead to higher overall costs, especially in scenarios that require large-scale deployment, where the cost disadvantage is more obvious.
Uncertainty in the economic and policy environment
Global economic fluctuations may affect budgetary investment in the military and communications sectors. For example, an economic recession may cause the government to cut defense spending, thereby reducing the purchase of SSPA. In addition, export control policies of various countries (such as the US export restrictions on GaN technology) may hinder the globalization of the market and increase the compliance costs of enterprises.
3 Technological Innovations in the Solid State Power Amplifiers (SSPA) Market
Breakthroughs in new materials and device structures
The maturity of GaN technology is the core of SSPA technology innovation. Manufacturers such as Qorvo and Wavestream Corp. have achieved higher power density and efficiency by optimizing the design of GaN devices. For example, Qorvo’s Spatium® technology uses 16 GaN MMIC power devices to synthesize, combined with broadband matching technology, to achieve a synthesis efficiency of up to 93%, covering broadband applications from L to Ka band. In addition, the introduction of silicon carbide (SiC) substrates further improves thermal management performance, allowing SSPA to operate at higher power and in harsher environments.
Modular and integrated design
To meet the needs of miniaturization and high reliability, manufacturers have launched modular SSPA products that integrate power, monitoring and heat dissipation components. For example, Diamond Microwave’s compact SSPA module weighs only 890 grams, integrates thermal monitoring and phase adjustment functions, and is suitable for airborne and spaceborne radars. Wavestream’s Endurance series achieves “plug and play” high-power amplification through modular design, simplifying the system integration process.
Software-defined and intelligent upgrades
With the rise of software-defined satellites (SDS) and intelligent communication systems, SSPA has begun to integrate digital pre-distortion (DPD) and adaptive algorithms to improve linearity and spectral efficiency. For example, Thales Group’s SSPA products support software configuration, which can dynamically adjust power output and frequency response to meet the needs of different communication protocols and satellite frequency bands.
Innovation in heat dissipation technology
To solve the heat dissipation problem under high power, manufacturers use microchannel liquid cooling, thermal interface materials (such as graphene) and three-dimensional packaging technology. For example, Empower RF’s liquid-cooled SSPA module uses a microchannel design to control the junction temperature below 230°C, ensuring the stability of long-term high-power operation.
Market consolidation of leading companies
Industry leaders expand their product lines and market share through mergers and acquisitions. For example, Qorvo acquired United Silicon Carbide in 2022, expanding its silicon carbide power device business and enhancing its competitiveness in high-frequency band SSPA. Teledyne Technologies acquired ETM-Electromatic, acquired its high-power microwave and X-ray subsystem technology, and strengthened its layout in the defense and medical fields.
