Application Context
Why Engineers Choose WHP 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.
WHP manufactures build-to-print coaxial cable assemblies for RF programs that need repeatable, documented production. Every assembly receives continuity and electrical testing; RF measurements and records follow the approved control plan, with sampling where the program test plan permits it.
From prototype assemblies for lab validation to recurring telecom production, capacity, material traceability, and release records are confirmed for the approved program. Production in China and the Philippines follows the customer drawing and program-specific control plan.

Engineering Challenges
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% continuity and hi-pot verification on every unit, plus sample pull-force testing per the control plan.

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 receives 100% continuity and electrical testing. VSWR, return loss, insertion loss, and dielectric testing are performed with calibrated equipment per the approved control plan, with sample or unit-level records supplied when required by the program test plan.
Can you build phase-matched coaxial cable assemblies?
Yes, we manufacture phase-matched assembly sets for antenna arrays and multi-channel RF test systems to customer drawings. Phase-match tolerances, measurement methods, and release records follow the quoted program test plan.
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.
Can you build with customer-specified connector cable and connector types?
We build to customer drawings that may identify IEC 61196 cable types, IEC 61169 connector types or IEC 60068 test methods. Those references define materials or acceptance methods only and do not represent end-market qualification.
