Beyond IMS 2026: High-Frequency Trends Shaping Next-Generation Design

Dedicated to advancing RF, microwave, and millimeter-wave technologies, the IEEE MTT-S International Microwave Symposium (IMS) once again showcased a shift toward higher frequencies, increased system-level co-design, and more demanding packaging and interconnect requirements. There is a clear convergence of high-frequency innovation across multiple industries, with drone technologies and quantum computing emerging as two of the most compelling areas of advancement. Both domains are pushing the limits of signal integrity, miniaturization, and high-speed data transmission.

As system complexity increases, so too does the demand for reliable, high-performance interconnect solutions capable of operating at higher frequencies and tighter tolerances. For connector manufacturers and system designers alike, these trends underscore a shared challenge: enabling next-generation performance without compromising reliability or scalability.

Drones: Expanding Applications, Increasing Design Demands

Drone platform development is being shaped by continued progress in RF front-end design, multi sensor and camera fusion, and autonomous navigation architectures. At IMS 2026, the conversation reflected a broader set of drone use cases beyond traditional imaging and surveillance, including industrial inspection, precision agriculture, logistics, and defense. These emerging drone applications place tighter constraints on size, weight, power, and reliability. These platforms depend on compact interconnect systems that preserve signal integrity across high-frequency paths while withstanding vibration, thermal cycling, shock, and other environmental stresses. Shielding is especially critical for sensor, camera modules and antenna boards. Advanced shielding techniques reduce electromagnetic interference, limit crosstalk, and maintain consistent RF and imaging performance in densely packed assemblies. In parallel, demand is rising for ultra-miniaturized connectors below 1.0 mm pitch to support higher component density, shorter routing lengths, and more efficient board real estate utilization without compromising electrical or mechanical performance. As edge AI processing becomes more common onboard, internal bandwidth requirements continue to increase, making low-loss, high-speed interconnects and robust EMI control essential to overall system performance.

Emerging drone applications also feature an emphasis on design flexibility. Expanded connector terminator options and complementary accessories that can better match the mechanical, electrical, and environmental needs of drone platforms. As layouts become denser and performance requirements become more specialized, engineers need a broader set of backshells, caps, board-side reinforcement features, and termination variants to support everything from controlled impedance routing to strain relief and environmental protection. Hirose continues to expand these options to simplify integration, improve assembly robustness, and give designers more control over EMI management, mating reliability, and system-level packaging in compact airborne platforms.

Quantum Computing: Supporting Next-Gen Cryogenic Environments

Quantum computing was another major focal point at IMS 2026, particularly in the context of RF and microwave signal control within quantum systems. Unlike conventional computing, quantum systems rely on extremely precise signal generation and measurement at cryogenic temperatures, introducing unique connectivity challenges. High-frequency coaxial connectors and cable assemblies must deliver exceptional signal integrity while minimizing thermal leakage and maintaining mechanical stability across extreme temperature gradients. Engineers are also addressing impedance matching and shielding requirements to reduce noise and interference, which can directly impact qubit coherence and system accuracy. As quantum computing moves closer to practical deployment, scalable and repeatable interconnect solutions will play a critical role in transitioning from laboratory environments to commercial systems.

Emerging 6G Networks

The development of 6G infrastructure was a dominant theme throughout IMS 2026, with a strong emphasis on frequencies extending into the sub-THz range. These higher frequencies promise unprecedented data rates and ultra-low latency but introduce significant design complexities related to signal loss, material selection, and connector performance.

Traditional interconnect approaches are being reevaluated as engineers seek solutions capable of maintaining performance at frequencies well beyond current 5G deployments. This includes the need for precision RF connectors with superior return loss characteristics, as well as advanced cable assemblies designed to minimize attenuation. Furthermore, system architectures are becoming increasingly dense, requiring connectors that support both high-frequency performance and high pin counts in compact footprints. These requirements are driving innovation in connector geometry, materials, and manufacturing processes.

Addressing Design Challenges

Across all these emerging applications, a common set of connectivity design challenges is becoming evident. Engineers must balance competing priorities such as miniaturization versus performance, high-frequency capability versus mechanical robustness, and system density versus thermal management. Signal integrity remains a central concern, particularly as frequencies increase and tolerances tighten. Even minor discontinuities in connector interfaces can result in significant performance degradation at microwave and millimeter-wave frequencies. Additionally, as systems become more modular and scalable, connectors must support repeated mating cycles without compromising electrical or mechanical performance. These challenges are further compounded by the need for faster development cycles and cost-effective manufacturing.

High-Frequency Solutions from Hirose

Hirose’s RF and microcoaxial connector portfolio meets the demands of next-generation systems where size, signal integrity, and reliability all matter. In applications such as drones and quantum computing, designers need interconnects that support compact layouts, stable high-frequency performance, and dependable operation in challenging environments.

The U.FL-Standard is a strong fit for compact RF designs because it is widely recognized for ease of use and straightforward integration into systems. That makes it appealing for drone platforms, where board space is limited and designers need connectors that simplify assembly without sacrificing performance. For higher-frequency needs, U.FL(a) extends that value by supporting use at elevated frequencies, making it a better match for RF paths that must preserve signal quality in more demanding wireless or sensing architectures.

The KMA01 brings an automotive-grade level of durability to RF connectivity, with the kind of reliability needed for harsh operating conditions and environmental stress. That resilience is relevant for drones, which can face vibration, temperature swings, and outdoor exposure, and it also matters in precision-oriented environments where a stable RF connection must hold up over time. In a quantum computing context, where systems are built around highly controlled and often densely packed hardware, a connector positioned for reliability helps support consistent performance and reduces risk in sensitive signal paths.

The DF36 stands out as a microcoaxial connector family designed for compact, high-density assemblies. Its shielding variation supports signal protection in applications where electromagnetic interference must be minimized, while its space-saving variation helps engineers fit more capability into less room. That combination is especially useful for drones, which increasingly integrate multiple cameras, antennas, sensors, and control links into very small enclosures, and for quantum computing systems, where tight integration and signal integrity are central design priorities.

Conclusion

IMS 2026 reinforced the critical role of advanced interconnect solutions in enabling next-generation technologies. Whether supporting the high-speed data links within drones, the precision RF environments of quantum computing systems, or the ultra-high-frequency demands of emerging 6G networks, connectors are no longer passive components—they are key enablers of system performance.

Moving forward, collaboration between connector manufacturers, system designers, and materials engineers will be essential to address evolving requirements and ensure reliable operation in increasingly complex applications.
