Custom Coaxial Cable Assembly Manufacturing Services
Precision-built RF coaxial cable assemblies from DC to 110 GHz. Expert connector termination, 100% VSWR tested, and delivered with full test certification. From prototypes to high-volume production.
Why Engineers Choose WellPCB for Coaxial Cable Assemblies
When signal integrity determines whether your system meets spec or fails qualification, your coaxial cable assemblies cannot be an afterthought. Every decibel of insertion loss, every point of VSWR, and every degree of phase stability matters — especially at frequencies above 6 GHz where marginal assemblies degrade system performance.
WellPCB manufactures custom coaxial cable assemblies for RF engineers who need repeatable, tested, and documented performance across thousands of units. Our IPC-certified technicians build with cables and connectors from leading manufacturers, and every single assembly ships with verified electrical test data — not sample-based lot testing, but 100% individual verification.
From single prototype assemblies for lab validation to production runs of 50,000+ units per month for telecom infrastructure, we deliver the same quality standard with full material traceability. Our five manufacturing facilities across four countries let you source locally while maintaining consistent specifications globally.

In RF cable assembly, the difference between a good product and a failed one often comes down to termination quality and testing rigor. We test every single assembly — not batches, not samples — because our customers' systems depend on consistent performance from the first cable to the ten-thousandth.
