Diversified Technologies, Inc. (DTI) operates in this space, focusing on the design and construction of high-voltage, high-power electronic systems for defense, radar, scientific research, and industrial applications.
“Our work is built on a solid-state switching architecture that enables precise control of high voltage and high power over long operating periods,” says Michael Kempkes, VP of marketing. “That same architecture gives us the flexibility to support a wide range of applications while maintaining reliability.”
The company’s foundation lies in the development of a patented solid-state switching technology. By combining low-voltage semiconductors in series and parallel, DTI has enabled multiple transistors to operate as a single switch, capable of handling high voltage and power. Today, nearly 90 percent of its work is built on this innovation, which continues to drive system performance across diverse applications. Initially used in high-energy physics and semiconductor environments that require precise pulse control, the technology has transitioned to radar systems, which are currently its largest market.
This architecture supports a wide range of operational requirements. Systems can be configured from a few kilovolts to 500 kilovolts and from low current levels to tens of kiloamps, allowing the company to support a wide range of vacuum tube applications, including traveling wave tubes, klystrons, and magnetrons. Such flexibility allows the same underlying technology to be configured for different requirements without relying on completely new system designs. Many of these systems remain operational for decades, demonstrating the design's durability.
About 85 percent of DTI’s work is focused on fully integrated transmitter systems. These systems integrate power supplies, modulators, controls, cooling systems, and supporting subsystems into a complete solution - from the power input to the RF output of a vacuum tube. They are deployed across ground-based, mobile, and shipboard environments.
The company primarily focuses on building systems and conducting research and development. A clear example of this work is the upgrade of the Cobra Dane radar. Originally built in the 1970s, the radar’s legacy transmitters had become difficult to maintain due to obsolete components. DTI deployed upgraded systems across all transmitter groups, supporting 96 high-power tubes. The upgrade improved reliability, reduced maintenance costs, and extended the radar’s operational life by several decades.
The company continues to grow steadily, supported by long-term contracts and a strong backlog, with annual growth projected at 15 to 20 percent. Hiring skilled engineers remains a constraint, particularly in specialized high-voltage engineering roles, but its focus stays on building reliable systems that deliver consistent performance and long-term support in demanding, mission-critical environments.
What Should Buyers Expect From High Voltage Pulse Modulators?
High Voltage Pulse Modulators should deliver more than just a voltage and current rating. They need to provide consistent pulse performance, fast rise and fall times, reliable fault protection and ongoing support after installation. In radar, accelerator and semiconductor applications, the wrong modulator can affect tube life, RF output or process consistency. Buyers should evaluate how a system handles arcs, varying pulse widths, cooling requirements and long-term component availability. Acceptance testing should reflect actual operating conditions, not just ideal laboratory results.
How Does Diversified Technologies, Inc. Fit This Power Electronics Category?
Diversified Technologies, Inc. fits the High Voltage Pulse Modulators category through its work in solid-state switching for demanding high-power applications. Its PowerMod technology uses FET or IGBT stacks with synchronized gate drives, allowing multiple devices to operate as a single switch. The company designs and manufactures high-voltage systems for defense, radar, scientific research and industrial applications, including pulse modulators, DC power supplies and RF transmitters. Its modulator portfolio supports operation from 10 kV to 200 kV at up to 5,000 A, with higher currents available through parallel configurations.
Why Does Pulse Control Matter in Radar and RF Systems?
Radar and RF systems rely on clean, repeatable energy delivery. High Voltage Pulse Modulators play a key role in how consistently a klystron, magnetron or other tube receives power, which can influence signal quality and system availability. Modern solid-state designs can also reduce dependence on older tube-based switching components that are costly to maintain. The real question is not simply whether a pulse fires, but whether it performs the same way every time. Small waveform variations can lead to larger issues with tuning, maintenance and system output.
What Design Factors Affect Long-Term Support?
Long-term performance depends on maintainability, component strategy and fault management. High Voltage Pulse Modulators built around modular solid-state switches are often easier to adapt than older designs that rely on thyratrons, spark gaps or difficult-to-source switching components. Engineering teams should also assess protection against overvoltage and overcurrent conditions, diagnostic capabilities, control-loop response and service accessibility. A system that is difficult to repair can become costly long before its electrical specifications become outdated. Documentation quality is also important, particularly when equipment remains in service for decades.
How Does Diversified Technologies, Inc. Approach Integrated Transmitter Work?
Diversified Technologies, Inc. often views High Voltage Pulse Modulators as part of a broader transmitter system rather than a standalone component. Its integrated solutions can combine power supplies, modulators, controls, cooling systems and related subsystems from power input through RF output in a vacuum tube. These systems are designed for ground-based, mobile and shipboard environments. One example is the Cobra Dane radar upgrade, where DTI supplied modernized systems across transmitter groups supporting 96 high-power tubes and helped extend the operational life of the radar.
How Should Engineering Teams Evaluate a Supplier?
Supplier evaluations should focus on real-world requirements rather than the data sheet alone. High Voltage Pulse Modulators should be assessed against voltage range, current requirements, pulse width, rise time, fault-clearing capability and retrofit considerations. Teams should also ask how a supplier supports installed systems, manages obsolete components, handles field modifications and maintains documentation. For modernization projects, the best choice is often the design that reduces maintenance demands while providing enough flexibility to support future system requirements.
