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.
