Application Context
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 two manufacturing facilities in China and the Philippines let you source locally while maintaining consistent specifications globally.

What determines RF assembly performance
Signal Integrity & Loss
Insertion loss, VSWR and return loss controlled across the rated band — especially above 6 GHz, where marginal assemblies degrade system performance.
EMI / RFI Shielding
Multi-layer braid, foil wrap and conductive jackets deliver shielding effectiveness exceeding 90 dB to keep external noise out of the signal path.
Impedance Control
Tight 50 / 75 / 93 Ohm tolerance held to ± 1 Ohm and TDR-verified, with custom impedance matching for specialized test and measurement builds.
Termination & Test Rigor
IPC-certified termination, 100% pull-force testing and full VSWR / continuity / hi-pot verification on every unit — not sample-based lot testing.

FAQ
Frequently Asked Questions
What types of coaxial cable do you work with?
We manufacture assemblies using the full range of coaxial cable types: flexible (RG-58, RG-59, RG-174, RG-316, RG-142), low-loss (LMR-100/200/400/600), semi-rigid (0.047" to 0.250"), conformable/hand-formable, and micro-coaxial cables. We source from leading manufacturers including Times Microwave, Huber+Suhner, and Belden to ensure consistent electrical performance.
What is your minimum order quantity for coaxial cable assemblies?
Our minimum order quantity starts at just 10 pieces for standard configurations. For prototypes and engineering samples, we accept orders from 1 piece with expedited 3-5 day turnaround. Production runs scale from hundreds to tens of thousands per month with volume pricing.
How do you ensure the RF performance of each cable assembly?
Every coaxial assembly undergoes 100% electrical testing including continuity verification, VSWR/return loss measurement using calibrated network analyzers, and dielectric withstand testing. For critical applications, we provide individual test reports with swept frequency data. Our test equipment is calibrated annually to NIST-traceable standards.
Can you build phase-matched coaxial cable assemblies?
Yes, we specialize in phase-matched assembly sets for antenna arrays, phased-array radar, and multi-channel test systems. We achieve phase matching to ± 1 degree at the specified frequency using precision cable cutting, TDR measurement, and iterative trimming. Each set ships with a phase match certificate.
What connector types can you terminate?
We terminate all standard RF connector families: SMA, 2.92mm (K), 2.4mm, 3.5mm, BNC, TNC, N-Type, SMB, SMC, MCX, MMCX, QMA, 7/16 DIN, and F-Type. We stock a wide range of straight, right-angle, bulkhead, and panel-mount configurations in both 50 Ohm and 75 Ohm impedances.
Do you provide MIL-spec coaxial cable assemblies?
Yes, we build coaxial cable assemblies conforming to MIL-DTL-17 (cable) and MIL-C-39012 (connectors). Our processes follow IPC/WHMA-A-620 workmanship standards and MIL-STD-202 environmental testing methods. We can provide assemblies with full military qualification documentation for defense programs.

From Our Founder
“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.”
Hommer Zhao — Founder & CEO, WellPCB
