Product details

It is a 50 Ohm RF interconnect rated to 18 GHz, built for RG-402 (.141" semi-rigid) cable.

The 1-1478930-0 is built for RG-402 (.141" semi-rigid) cable. The shield terminates via solder, and the center contact is also solder-terminated. The kit includes the connector body, one contact, and one ferrule — three pieces total, bulk packaged. The dielectric is PTFE, which keeps insertion loss stable across the 18 GHz band and handles the soldering heat during assembly without degrading.

Construction and Mounting

Panel mount with a flange, threaded for the mating plug. The stainless steel body carries a gold finish — stainless gives the mechanical strength for the threaded coupling under torque, and the gold layer protects the mating interface from oxidation over the 500-cycle life. The center contact is beryllium copper with gold plating, chosen for spring properties and low contact resistance at RF frequencies.

Frequently asked questions

What cable does 1-1478930-0 fit?

The 1-1478930-0 is designed for RG-402 (.141" semi-rigid) cable. It is not specified for RG-316 or other cable types — the interface dimensions and ferrule are specific to the.141" diameter semi-rigid construction.

What is the impedance of 1-1478930-0?

The 1-1478930-0 is a 50 Ohm SMA jack, rated to 18 GHz. The impedance is set by the PTFE dielectric and the geometry of the center contact and outer conductor.
