Product details

RF interconnect for 50-Ohm lines up to 6 GHz

The Samtec MMCX-J-P-H-ST-SM1-K-TR is a 50-Ohm MMCX jack (female socket) built for surface-mount reflow assembly. It carries a snap-on fastening interface that mates with standard MMCX plugs — the same push-to-engage, pull-to-disconnect coupling used in compact RF modules, GPS receivers, and cellular radio chains. Rated to 6 GHz, this jack sits at the practical ceiling for the MMCX form factor — beyond that frequency the VSWR climbs and the subminiature shell starts to radiate.

What the 6 GHz ceiling means for your signal chain

The 50-Ohm impedance and 6 GHz max frequency determine RF path suitability. Below 6 GHz the snap-on mate allows quicker field swaps than a threaded SMA. The surface-mount solder termination allows the centre pin and ground shield to reflow in one pass. The pad layout must match the Samtec drawing to maintain the 50-Ohm launch.

Frequently asked questions

Is MMCX-J-P-H-ST-SM1-K-TR compatible with standard MMCX mating plugs?

Yes. This is a standard MMCX jack (female socket) with a snap-on fastening interface. It mates with any MMCX plug that follows the industry-standard interface — the same push-to-engage, pull-to-disconnect coupling used across the MMCX ecosystem. No special keying or locking variation.
