Cable selection lesson

An RF jumper needs impedance, loss and power evidence

Choose the exact assembly for the operating frequency and impedance. An SMA shell does not determine insertion loss, RF power handling or RP-SMA compatibility.

Applies to: Exact public table inspected; no VNA, insertion-loss or RF-power test.

Supported exact facts

The public product table identifies this assembly as50Ω RG316 with straight SMA plugs,305mm length and3GHz maximum frequency. It explicitly has no IP rating. These are exact-product statements, not measured performance.

Worked selection enquiry

For a declared1GHz50Ω instrument path,305mm is the selected assembly length and1GHz lies within its published frequency field. Acceptance still needs the source/load manuals, ordinary SMA-jack mate specification, required insertion loss and permitted RF power or DC bias. Do not power an unresolved path.

Unknown loss is not zero loss

The product table does not give insertion loss, and the linked customer drawing leaves its insertion-loss field blank. Do not substitute a connector-only insertion-loss value or a generic RG316-per-meter value as the assembly's guarantee. Request exact assembly loss and power at1GHz or a manufacturer test report.

Useful alternative

If this enquiry cannot obtain sufficient loss/power evidence, select a different documented assembly with those fields. Physical SMA mating and an under3GHz use case alone do not prove the RF path. A75Ω video assembly or RP-SMA center contact is a different selection.

Your next useful observation

Record the exact model, selected length, both endpoint roles and required application. Keep undocumented properties unknown.

Keep these limits

  • The selected SMA assembly does not establish numerical insertion loss; obtain its exact loss/power evidence. The separate precision-assembly example teaches documented loss interpretation without transferring values between products.
