RG-6 vs RG-59 coax: select by loss budget, bend room, and termination risk
RG-6 and RG-59 are both 75 ohm coax families, but they do not behave the same in a finished assembly. The practical selection comes down to attenuation, routing space, connector tooling, and test coverage.

RG6 vs RG11: distance, loss budget, and production tradeoffs
RG6 and RG11 are both 75 ohm coax families, but they do not behave the same in long runs, tight enclosures, or production. Here is how to choose between them before the BOM is frozen.

RG58 vs RG59: 50 ohm RF coax vs 75 ohm video coax in OEM assemblies
RG58 and RG59 are not interchangeable BOM lines. The right choice depends on impedance, connector geometry, loss budget, strip program, and the test record your customer will accept.

RG58 coaxial cable: when 50 ohm legacy coax still belongs in the BOM
RG58 is not a universal RF cable. It is a 50 ohm coax choice that still fits short industrial, test, and antenna runs when the drawing controls connector fit, strip length, bend radius, and VSWR test limits.

RF connector types by impedance, frequency, and assembly risk
SMA, SMB, BNC, TNC, FAKRA, MMCX, and U.FL fail for different reasons. This field guide maps connector type to impedance, frequency range, mating cycle expectations, cable geometry, and production controls.

Coaxial cable types and specifications for production RF assemblies
RG-58, RG-174, RG-316, RG-6, FAKRA, and micro-coax callouts fail when impedance, length tolerance, strip geometry, and test limits are left open. Here is the drawing-level spec set that prevents RF rework.

Coaxial cable transmission speed: delay, bandwidth, and test limits
Coax transmission speed is not a single Gbps number. Here is how velocity factor, cable loss, impedance, connector geometry, and RF test limits decide whether a coax assembly passes at 6 GHz or fails after continuity.

Coaxial cable ratings that decide whether an RF build passes
Impedance, frequency, VSWR, attenuation, voltage, jacket temperature, and bend geometry are not interchangeable rating lines. This guide shows what to lock before quoting a coaxial cable assembly.

Coaxial cable design rules that prevent impedance and shield failures
A practical design checklist for OEM coaxial assemblies: impedance, cable family, shield termination, connector fit, drawing callouts, and production tests that catch high-impedance failures before shipment.

Coaxial cable connector types by impedance and assembly risk
SMA, BNC, TNC, FAKRA, MMCX, U.FL, and I-PEX micro-coax are not interchangeable. Select by impedance, frequency, mating environment, strip geometry, and the failure mode your production line can actually control.

Coax Cable Standards: RFQ lines that prevent impedance and test escapes
Coax standards are not one clause. Impedance, cable construction, workmanship class, shield termination, and test method all need separate acceptance language before production starts.

RFQ checklist: 11 items that cut cable-assembly quote turnaround from 2 weeks to 24 hours
After 23 years quoting cable assemblies, the single biggest predictor of fast quote turnaround is the quality of the RFQ. Here are the 11 items that, if present in the first email, mean we send a quote the next business day.
