Product details

Why the 18 GHz Rating Matters

The 1050769-1: The 18 GHz max frequency means this plug covers the full DC-18 GHz band, which includes L, S, C, X, and Ku bands. For a semi-rigid cable assembly, the limiting factor is usually the connector launch — the PTFE dielectric and gold-plated beryllium copper centre contact keep the impedance transition clean through the solder joint to the cable centre conductor.

Cable Fit and Termination

This plug is built for RG-405 (.085" semi-rigid) cable — the most common 50 Ohm semi-rigid for microwave assemblies. The free-hanging (in-line) mounting style means it is used as a cable-end plug, not a panel jack.
