Product details

SMPM Jack for 40 GHz Semi-Rigid Cable Runs

The 925-134J-51S: It comes as a three-piece assembly — connector body, contact, and insulator — for field assembly onto 0.047" semi-rigid cable. The snap-on fastening and bulkhead front side nut make it a panel-mount design, with the gold body and gold center contact plating providing corrosion resistance and consistent RF performance through the rated 100 mating cycles.

What the 40 GHz Rating Means for Your Signal Path

40 GHz maximum frequency means this connector supports Ka-band and many mmWave applications without significant roll-off.

Cable Fit and Assembly

This jack is designed for 0.047" semi-rigid cable. The solder shield termination and solder contact termination require a clean, controlled solder joint — semi-rigid cable's solid outer conductor gives a reliable ground connection when properly tinned. Assembly is straightforward: strip the cable, solder the center contact, slide the insulator, and solder the body to the cable shield.

Frequently asked questions

What cable does 925-134J-51S fit?

This SMPM jack is designed for 0.047" semi-rigid cable. The solder shield and contact terminations require that cable type for proper assembly and RF performance.

Is 925-134J-51S compatible with RG178 cable?

No. The 925-134J-51S is specified for 0.047" semi-rigid cable only. RG178 is a different diameter and construction — it will not fit the solder termination or maintain 50 Ohm impedance through the interface.
