The transition from cable to PCB is one of the easiest places to lose performance margin. Small impedance discontinuities, inconsistent soldering interfaces, weak mechanical support, or poor ground continuity can introduce mismatch, loss, and long-term reliability issues—especially as frequency increases. Teledyne Storm Microwave’s PCB connector solutions help teams create cleaner, more repeatable transitions from coaxial cable assemblies to board-level circuits.
These connectors are selected to support predictable RF behavior while also addressing practical build realities such as board stack-up, mounting method, and mechanical retention. The goal is to make the connector interface easier to integrate, easier to inspect, and more stable over time—so performance in the lab is much closer to performance in the field.
PCB connector choices often come down to tradeoffs: size versus power handling, frequency coverage versus mechanical strength, and installation speed versus rework risk. Teledyne Storm Microwave supports connector solutions that align with both prototype needs and production requirements, helping customers standardize interfaces across programs and reduce the chances of late-stage redesigns. When paired with the right cable assembly and routing approach, PCB connectors become a dependable part of the RF chain rather than a recurring failure point.
-
What is an RF PCB connector and why is it important?
An RF PCB connector provides the transition from a coaxial cable to a printed circuit board transmission line. It’s important because that transition can strongly affect impedance continuity, insertion loss, return loss, and long-term reliability.
-
What problems do PCB connectors typically solve in microwave systems?
They create a controlled, repeatable cable-to-board interface that helps reduce mismatch and mechanical failures. A well-chosen connector can also simplify assembly, inspection, and field service compared to improvised transitions.
-
How do I avoid performance loss at the cable-to-PCB transition?
Start by selecting a connector compatible with your frequency range and PCB geometry, then ensure proper grounding and launch design. Consistent installation practices and mechanical support also help reduce variability and failure risk.
-
Are PCB connectors more sensitive at higher frequencies?
Yes. As frequency increases, small discontinuities and layout details become more significant, which can impact return loss and insertion loss. Connector selection and launch design become increasingly critical to protect margin.
-
Do PCB connectors support both test equipment and embedded system designs?
Yes. Test setups often prioritize repeatability and connector durability over many mating cycles, while embedded designs may prioritize compact size and mechanical retention. The best connector choice depends on how the interface will be used.
-
What information should I provide to select the right PCB connector?
Share your frequency range, board thickness/stack-up constraints, transmission line type (microstrip/stripline), connector orientation, and mechanical limits. If you have return loss goals or power handling needs, include those too.
-
Can Teledyne Storm help standardize PCB connector interfaces across programs?
Yes. Standardizing connector interfaces can reduce part proliferation, speed up procurement, and improve repeatability across builds. It also makes cable assembly reuse and platform-level integration easier.
-
How do mechanical factors affect PCB connector reliability?
Cable strain, vibration, and repeated mating can stress solder joints and mounting points. Good retention, proper strain relief, and robust mechanical design help prevent intermittent faults and early failures.
-
Do PCB connectors require special launch or grounding considerations?
Often, yes. Ground continuity, via placement, and launch geometry can impact impedance and reflections. Following recommended PCB footprint guidance and validating with simulation or measurement helps protect performance.
-
Can you support prototype-to-production needs for PCB connectorized assemblies?
Yes. The same interface strategy can be validated in prototypes and then carried forward into production builds to reduce redesign risk. Clear documentation and consistent assembly practices help keep performance repeatable.
-
What’s a common mistake teams make with RF PCB connector implementations?
Assuming the connector is “plug-and-play” without accounting for the PCB launch and mechanical loads. Most issues come from footprint/grounding choices, inconsistent installation, or strain that wasn’t designed out.
-
How can PCB connectors help reduce rework and debug time?
A repeatable, inspectable interface reduces variability, so failures are easier to isolate and fix. That can significantly shorten debug cycles compared to ad-hoc soldered cable transitions.
-
Are PCB connectors useful for high-density or space-constrained RF designs?
Yes. Many applications need compact, mechanically stable connectors that still support high frequency performance. Selecting the right form factor helps preserve routing space and reduce board-level congestion.
-
How do I request a recommendation for PCB connectors from Teledyne Storm?
Provide your target frequency range, connector orientation, board constraints, expected mating cycles, and environmental conditions. If you can share a board outline or interface control details, that speeds up selection.
