Cable selection lesson

Keep RF length and frequency attached to loss

A usable loss example identifies assembly construction, length and frequency together. A connector's de-embedded loss or a neighboring length's result cannot substitute for the cable you select.

Applies to: Primary manufacturer performance example; no VNA or RF-power test.

Named manufacturer example

AmphenolCIT's SS-10259-052024 describes its0.047in flexible coax assemblies with1.00mm male connectors. The assembly specification gives50±1Ω. It separately shows measured35cm assemblies and lists a31cm orderable assembly, TM4SM1MS1MS0031.

Two source-scoped loss readings

In the35cm column, the manufacturer's insertion-loss-variation table reports-1.59dB at2GHz and-4.15dB at40GHz. These are the source's signed example values for that construction and length; they are not measurements made here or guaranteed limits for the31cm orderable SKU. No value is interpolated for another frequency.

Complete selection enquiry

Declare the two equipment ports, compatible1.00mm female interface, required50Ω path, selected assembly length and operating frequency. The source lists board-jack examples such as TMB-E1F2-1L1 within the solution, but an exact mating/interface drawing and RF-power conditions must still be checked before use. No energized probing or board assembly is taught here.

Contrast that changes the decision

The source's board-connector insertion loss is explicitly de-embedded connector loss. It cannot be assigned to the full cable. Likewise, the AmphenolRF305mmRG316SMA example is a different construction whose loss remains unknown; do not borrow the1mm-family values.

Your next useful observation

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

Keep these limits
