1. What are the primary markets you address with your high-power products?
At Integra, we focus on mission-critical, high-performance markets including airborne, shipborne and ground-based radar; air traffic control; and avionics applications. These are all high-stakes applications where RF high power, efficiency and thermal management are first-order system drivers and device-level performance directly impacts platform survivability and operational advantage.
With the introduction of our groundbreaking High-Voltage Gallium Nitride on Silicon Carbide (HV GaN/SiC) platform, Integra has enabled dramatic leaps in next-generation system performance in our primary markets while expanding our technical reach into emerging mission-critical applications such as High-Power Microwave (HPM) and Directed Energy systems. Integra is also seeing significant traction in Industrial, Scientific & Medical (ISM) domains — particularly high-energy physics and particle accelerators — where multi-kilowatt HV GaN/SiC based solutions enable practical solid-state replacements for Vacuum Electron Devices (VED) for the first time in our industry.
2. How has Integra Technologies adapted with market changes over the last few years?
The pace of change in our markets has accelerated dramatically, and today’s platforms demand unprecedented levels of efficiency, RF power, configurability and reliability. As system requirements have evolved, so has our role with customers. A major driver of this shift has been the breakthrough capability of Integra’s HV GaN/SiC technology. Because these devices enable true leap-ahead system re-architecting, customers want us engaged much earlier in the design cycle — often as part of their system architecture team rather than as a traditional component supplier.
To support this level of collaboration, we have significantly expanded our investment in high-voltage device physics, next-generation packaging, advanced manufacturing techniques and system engineering. We’ve also strengthened our modeling and simulation infrastructure, enabling deep co-design with customers at the electrical, thermal and mechanical levels. This early partnership approach ensures that our solutions not only meet the needs of current platforms but actively shape the architectures of next-generation systems.
We have additionally enhanced our product capabilities by integrating digital control features into our HV GaN/SiC portfolio, giving customers new levels of dynamic power configurability and system-level intelligence.
Operationally, we have modernized our engineering and production environments with advanced tools, improving development speed, manufacturing predictability and end-to-end quality.
Collectively, all these innovations — combined with the transformational nature of our HV GaN/SiC technology—have positioned Integra as a strategic partner for customers designing the highest-performance RF power systems of the future.
3. What is the status of your high-voltage GaN process, and how has it progressed over the years?
Integra launched the industry’s first 100 V HV GaN/SiC product in 2021 and began production shipments in 2022. Since then, we have built a broad portfolio across all major frequency bands. We are now on our fourth generation of the platform, supporting both 100 V and 125 V operation. These products are actively deployed in U.S. and European defense systems, as well as several ISM applications.
Our technology has demonstrated exceptional stability under high thermal load, extreme VSWR conditions and demanding pulse conditions — performance characteristics that are essential for modern high-power high-performance systems.
Integra is currently executing its third Department of Defense contract focused on advancing and maturing our fifth-generation 150 V HV GaN/SiC technology. This process will establish a new bar for industry-leading power density and RF high-power performance. Looking ahead, we continue to evaluate even higher-voltage variants to support future architectures that require greater power capability without compromising efficiency, ruggedness or reliability.
Our roadmap ensures that Integra remains ahead of system-level power and voltage requirements as next-generation platforms continue to push technical boundaries.
4. What type of thermal solutions are needed for such high-power transistors, and how do you address these challenges?
Managing thermal performance is one of the most critical challenges in high-power RF transistor design, particularly as voltage and RF power continue to rise. Leveraging Integra’s three decades of thermal management expertise and IP; Integra has developed new materials and patented multiple thermal-enhancement structures that directly address these constraints.
In addition to our know-how and patented IP, Integra’s technical teams have developed a proprietary electrical and thermal co-modeling environment that enables us to simulate and optimize thermal resistance at the semiconductor chip design stage. This tool enables us to predictively engineer an optimized thermal solution on the first design pass. It also gives us the flexibility to tailor solutions to specific mission profiles or unique customer system conditions. More importantly, it enables true real-time system trade-off analysis in the simulation space, allowing customers to balance performance, size, cost and reliability before hardware is ever built. The result is accelerated development cycles, higher first-pass success rates, lower engineering costs and faster time-to-market for our customers.
These innovations ensure that device junction temperatures remain within safe operating limits, enabling multi-kilowatt-class operation with long-term reliability.
5. How does your technology change system architecture and improve SWaP-C²?
SWaP-C² — Size, Weight, Power, Cost and Complexity — is the framework we use to quantify the architectural impact of Integra’s HV GaN/SiC technology. One of the biggest shifts we’ve introduced is reframing the value metric from dollars per transistor watt to dollars per system watt. This system-level lens captures the full benefit of the architectural simplification enabled by operating at 100 V and above.
A single 100 V GaN/SiC device can replace multiple LDMOS or 50V GaN transistors in a traditional power-combined architecture. That consolidation removes entire layers of splitters and combiners, simplifies bias and control circuitry, reduces thermal management requirements and dramatically shrinks the physical footprint. The cumulative effect is a platform that is smaller, lighter, more power-efficient, and significantly less expensive to design, integrate and maintain.
Equally important, reducing architectural complexity — the second “C” — enhances system robustness. Fewer RF combining stages reduce combing loss, improve reliability and enable new PA topologies that simply aren’t feasible at 50V. HV GaN/SiC gives system architects the freedom to rethink platforms at a foundational level rather than incrementally improving legacy designs.
For example, one major scientific customer evaluated what it would take to create a solid-state replacement for a megawatt-class VED. Their initial analysis showed they would need nearly 2,000 LDMOS transistors to reach the required output power — an architecture so large, complex and thermally demanding that it was effectively impractical. When they reassessed the design using Integra’s HV GaN/SiC technology, the entire equation changed. The same megawatt-level output could be achieved with roughly 250 of Integra’s HV GaN/SiC transistors.
This reduction — an order-of-magnitude fewer devices — transformed the system architecture:
- The number of transistors became manageable to combine efficiently and reliably.
- They eliminated the need for massive capacitor banks, bulky step-down transformers and hazardous kilovolt-level power supplies.
- Overall system reliability improved significantly, with higher MTBF and far fewer potential points of failure.
- It resolved looming supply-chain challenges tied to end-of-life technologies.
This is a clear illustration of how Integra’s HV GaN/SiC solution collapses system complexity, reduces component count, and delivers meaningful SWaP-C² gains — enabling architectures that would be impractical, or impossible, with legacy technologies.
6. How does your technology enable VED replacement with SSPA technology, and what advantages does that provide?
Our HV GaN/SiC platform delivers the RF high power and efficiency required to replace VEDs — magnetrons, klystrons and TWTs — with Solid-State Power Amplifier (SSPA) architectures. For the first time in our industry, a single transistor can achieve output power levels that make solid-state alternatives viable without unmanageable RF combining or architectural compromises.
VEDs have historically provided high power but with significant trade-offs: large form factors, heavy and complex high-voltage power supplies, limited lifetimes and costly maintenance cycles. HV GaN/SiC SSPAs provide a fundamentally different value proposition:
- waveform agility and dynamic control
- substantially higher reliability and MTBF
- graceful degradation rather than catastrophic failure
- long-term technology viability
- simplified logistics and maintainability
- lower total cost of ownership across multi-decade programs
For radar, HPM, directed energy and ISM applications, HV GaN/SiC is now the most credible, scalable path to full solid-state transformation.
7. How have you incorporated digital technology into your products?
Digital enablement is now a core pillar of our product strategy. We’re designing intelligent digital control, telemetry and diagnostics directly into our high-power RF pallets-amplifiers. These features provide:
- real-time device and system health monitoring
- automatic calibration and performance optimization
- built-in self-test and fault isolation
- adaptive power control and protection mechanisms
- integration with modern system controllers
This digital layer dramatically reduces system engineering effort and gives customers a more deterministic, repeatable transition from prototype to qualified, fielded systems.
8. What partnerships are you leveraging to address system needs, and how has that positioned the company?
We are collaborating closely with leading defense primes, subsystem integrators, semiconductor partners and government research laboratories to ensure tight alignment between device capability and emerging mission requirements. These collaborations accelerate validation of our HV GaN/SiC at the module, subsystem and full-system levels, while helping customers de-risk their transition from legacy architectures.
This ecosystem approach strengthens our market position and ensures our technology roadmap remains synchronized with the next generation of high-performance high-power RF and microwave platforms.
9. What future plans do you have for technology and how do you see it progressing over the next five years?
We will continue to push the boundaries of HV GaN/SiC, driving higher operating voltages, broader instantaneous bandwidths and enhanced ruggedness across UHF through X-band.
A central focus of our roadmap is advanced functional integration — bringing high-power devices, thermal structures, broadband matching networks and embedded digital intelligence into compact, system-ready pallet-amplifiers. This deeper integration will accelerate the adoption of HV GaN/SiC solid-state architectures in RF and microwave high performance systems and multiply SWaP-C² benefits.
Our commitment is to lead the industry through the next wave of RF power innovation — ensuring our customers have the enabling technology required for future defense, aerospace and ISM applications.
