Powering HPM Systems with Hermetic and RF Solutions

In the RF and microwave community, one thing is clear: Future systems must work accurately. They also need protective features and strong power performance in tough environments. Aptiv confronts these challenges with specialized interconnect technologies designed for high-power microwave (HPM) and other critical missions.

Aptiv provides several ways to help customers who design systems for electronic warfare, radar, space, or reliable communications. This support helps them stay ahead in their fields.

Hermetic Packaging That Goes Beyond the Seal

Modern microwave systems feature reduced size and increased density while functioning under more extreme environmental conditions than before. Sensitive electronics benefit from Aptiv's hermetic packaging solutions that reduce signal loss and EMI while preventing environmental damage.

• Ceramax^® Dielectric: A proprietary multiphase ceramic that replaces glass for superior long-term reliability. Supports extreme operating temperatures from -269°C to +450°C with sealing performance down to 1 x 10⁻⁹ atm cc/sec.
• Titanium-Aluminum Packaging (TAP): Balances strength, thermal conductivity, and weight for thermal-sensitive modules in lightweight applications—ideal for airborne and space systems.
• Vacuum Brazing, Laser Beam Welding (LBW), and Explosion Welding (EXW): Enable seamless integration of dissimilar metals for flexible housing configurations.

Our systems design provides increased adaptability while ensuring extended operational life spans regardless of extreme environmental conditions.

Absorb More. Fail Less. Total System Protection in One Sealed Cover

For compact microwave packages where performance and protection are non-negotiable, Aptiv's hermetically sealed cover assemblies go further:

• PolyIron^® Microwave Absorber: Absorbs EMI at the source—unlike reflective shielding—keeping internal circuitry at peak performance.
• Hydrogen Getter Integration: Actively seizes any remaining hydrogen to prevent damage to internal parts which is crucial in vacuum settings.

The combination of these technologies results in a fully engineered enclosure solution, which protects the system while enhancing its operational integrity for the long term—a vital feature for densely packed HPM modules.

RF Connectors Built for Power and Precision

Aptiv's RF and microwave assemblies are engineered to ensure signal integrity, even in the most unforgiving conditions:

• Quick-Disconnect Series (QDS/QRM): Rugged, high-voltage connectors with quick-disconnect functionality for rapid maintenance and modular system design.
• Corona and Arcing Resistance: Designs prioritize precise creepage paths and material selection to mitigate electrical breakdown in high-voltage environments.
• High-Frequency Hermetic Feedthroughs: Available in SMP, SMPM, SMA, SSMA, TNC, and Centurion styles for demanding RF chain integration.

Our full suite of RF cable solutions includes:

• SpaceFlex^® – Space-grade coaxial cable assemblies
• ArcTite^® – Ultra-low-profile bends for tight packaging constraints
• TRUflex™ PWR Series – High-power coax
• PhaseTite^® – Temperature-stable phase-matched solutions
• DynaFlex^® – Ruggedized and weather-resistant cables

With build-to-print capabilities, matched phase delay, and high-voltage interface engineering, we deliver more than components—we deliver full system compatibility.We provide comprehensive system compatibility, going beyond just components, through build-to-print services, matched phase delay solutions, and specialized high-voltage interface engineering.

When Small Size Delivers Big Performance

Modern systems require compact weight to function optimally particularly when operating at 60,000 feet or in electronic warfare situations. Aptiv's Ulti-Mate™ Micro and Nano D connectors along with their assemblies deliver high-density connections in small and robust form factors.

• M83513- and M32139-approved designs
• Hermetic mating options
• SMT and PCB mountability
• Available as complete cable assemblies

These components are suitable for control modules, sensors, and compact payloads where failure is not an option.

Built for the Industries Where Failure Is Not an Option

Aptiv solutions serve critical markets like:

• Aerospace & Defense
