During the historic period, growth was driven by the expanding role of high power microwave generators in critical infrastructure protection, rising demand for non-kinetic warfare solutions, increased use in material processing and sterilization, growing applications in plasma research, and greater integration of directed energy weapons in defense systems.

The high power microwave generator market size is expected to see strong growth in the next few years. It will grow to $2.16 billion in 2029 at a compound annual growth rate (CAGR) of 8.6%. In the forecast period, growth is expected to be driven by increasing adoption of vehicle-mounted high power microwave systems, rising demand for high-energy pulsed power systems, growing cross-border security threats prompting HPM deployment, expanding industrial use for high-temperature plasma applications, and the rise of space exploration missions utilizing microwave technologies. Key trends during this period include miniaturization of high power microwave sources for mobile platforms, integration of solid-state microwave components into HPM systems, adoption of AI-based control for pulse shaping and frequency tuning, and advancements in thermal management and cooling systems for HPM devices.

The rising defense budgets are expected to drive growth in the high-power microwave generator market. Defense budgets, which allocate funds for purchasing, replenishing, and maintaining military equipment and munitions, are increasing due to growing global security threats and the need to modernize armed forces. High-power microwave generators play a key role in electronic warfare and directed-energy applications. For example, in 2022, the UK secured defense orders worth $16.04 billion (£12 billion), a rise of $6.15 billion (£4.6 billion) from 2021, according to the House of Commons Library. The expanding defense expenditure supports the development, deployment, and technological advancement of HPM systems.

Companies in the high-power microwave generator market are focusing on innovative solutions, such as solid-state GaN-based microwave generators, to support applications in RF energy, plasma generation, hydrogen production, and industrial processing. Solid-state GaN generators use gallium nitride semiconductor technology to produce microwave-frequency signals with high reliability and efficiency. For instance, in August 2024, Elite RF LLC, a US-based electronics manufacturer, launched a line of solid-state GaN-based HPM generators operating in the 2.4-2.5 GHz range, with outputs of 3 kW, 6 kW, and 12 kW. These devices replace traditional magnetron tubes with digital, field-repairable designs featuring RF redundancy, smart power control, and automatic power adjustment. Applications include plasma generation, CVD diamond production, hydrogen generation, and coatings, with flexible control options via touchscreen, RS-232, or Modbus.

In October 2022, MUEGGE GmbH, a Germany-based electronics manufacturer, acquired LEANFA srl, an Italy-based company specializing in solid-state microwave and high-frequency generators. This acquisition strengthened MUEGGE’s high-frequency capabilities, expanded its solid-state HPM product line, improved efficiency and reliability, and created new opportunities in healthcare, reinforcing its position in advanced high-frequency solutions.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid rise in U.S. tariffs and the subsequent trade frictions in spring 2025 are having a major impact on the electrical and electronics sector, with semiconductors, display panels, and rare-earth metals (essential for batteries and motors) subject to steep duties. Consumer electronics brands face profit erosion, as competitive markets limit their ability to pass costs to buyers. Industrial electronics manufacturers, meanwhile, grapple with delayed projects due to shortages of tariff-impacted components like printed circuit boards. Companies are responding by relocating assembly to tariff-exempt countries, increasing inventory buffers, and redesigning products to reduce dependency on restricted materials.

A high power microwave generator is an advanced device that produces intense microwave energy for use in defense, scientific, and industrial applications. It can emit high-intensity pulses or continuous waves, making it suitable for disabling electronics, powering radar and communication systems, conducting plasma research, and performing high-energy material processing.

The main types of high power microwave generators are continuous wave generators and pulsed generators. Continuous wave generators provide a constant, uninterrupted microwave signal, which is essential for applications requiring stable, continuous energy output. These generators are available in various forms, including switch mode, solid state, and magnetron types, and in different power levels such as low, medium, and high power. They are used in applications across industries such as semiconductors, medical treatments, and food processing, and serve sectors including healthcare, defense, telecommunications, manufacturing, and more.
