Space programs punish weak interconnect decisions. A cable that looks fine on a bench can drift in phase with temperature swings, degrade insertion loss margins when routed tightly, or fail early from handling, vibration, and integration stress. Teledyne Storm Microwave addresses these realities with high-performance coaxial cable assemblies engineered for stable microwave behavior and durable mechanical performance in space and other harsh environments.
These assemblies are selected and configured to help satellite and payload teams maintain predictable RF paths across the mission lifecycle—from development and qualification through integration and deployment. The goal is straightforward: reduce calibration drift, preserve link budgets, and minimize rework caused by late-stage interconnect problems. Options can be tuned to balance attenuation versus diameter, stability versus flexibility, and ruggedness versus routing constraints so the RF chain behaves as intended in real conditions.
Storm’s engineering engagement is designed to help customers get to “best fit” quickly—especially when requirements conflict (tight bend radii, low loss, high frequency, extreme temperature range, and strict packaging). Teams can request phase matching for critical paths and can tailor construction choices such as jacket material, conductor/dielectric selections, braid protection, and overall diameter to align with performance and durability goals.
-
What problem do high-performance space cable assemblies solve?
They help maintain stable RF performance when temperature swings, vibration, and tight routing would otherwise degrade signal integrity. The payoff is fewer surprises during qualification and more predictable system performance in flight-like conditions.
-
How do I know if I need phase-stable RF cable assemblies?
If your system relies on calibration, timing, beamforming, or repeatable phase response, phase stability becomes a key requirement. It’s especially important when operating temperatures vary widely or when long RF runs are involved.
-
Can you help protect link budget and insertion loss margins?
Yes. Solutions can be selected to minimize attenuation for the required frequency range, while balancing diameter and routing constraints. This helps preserve link margins and reduce compensation needs elsewhere in the RF chain.
-
What makes these assemblies suitable for space and harsh environments?
They’re configured for stability with temperature change, mechanical robustness under extreme conditions, and long-term durability. Construction choices are used to align electrical performance with the mechanical realities of integration and operation.
-
We have very tight routing space—can you still deliver low-loss performance?
Yes. Storm supports high-frequency, single-cable alternatives and offers construction options to optimize attenuation versus diameter when routing is constrained. Sharing bend, diameter, and packaging limits helps identify the best-fit approach.
-
Do you offer phase matching for multi-channel payloads or critical RF paths?
Yes, phase matching is available on request. Provide your tolerance, frequency range, and operating conditions so the build and verification approach aligns to your requirement.
-
What can be tailored in the cable construction?
Options may include jacket material, center conductor configuration, dielectric core selection, outer conductor choices, protective braid, and overall diameter. These variables help balance stability, flexibility, ruggedness, and RF loss.
-
Can you support programs from prototype through qualification and production?
Yes. Storm supports development builds and can carry the configuration forward as programs mature, helping maintain consistent RF behavior and build repeatability through production.
-
How early should we involve engineering support?
Early engagement—during architecture and packaging decisions—reduces the chance of late-stage routing or connector conflicts. It also helps align cable selection with thermal, mechanical, and RF budgets before schedules tighten.
-
Are these assemblies only for flight hardware, or also for ground systems and test?
They can support mission-critical ground systems and test environments where stability and repeatability matter. Selecting the right construction for the use case helps maintain consistent measurement performance and durability.
-
What information should I provide to get the right recommendation?
Share frequency range, length, power level, connector interfaces, routing constraints (bend radius/diameter limits), temperature range, and whether phase matching is required. If you have loss targets or mass/volume limits, include those too.
-
What’s the advantage of using a single-cable alternative at high frequency?
It can simplify routing, reduce interfaces, and improve reliability when packaging is tight. Fewer transitions can also help preserve performance by reducing mismatch and integration variability.
-
How does mechanical durability affect RF performance over time?
Handling and flexure can change cable behavior if the construction isn’t designed for stability. A durable, application-appropriate build helps maintain performance over repeated integration cycles and mission life.
-
Do you have space-flight heritage or qualification experience?
Yes. Storm’s space flight heritage traces back to the 1990s, and since 2010 the company has dedicated design, engineering, test, qualification, and documentation resources for space customers.
