The MMCX jack that handles vibration without losing the signal path
The Samtec MMCXV-J-P-GF-ST-TH1 is a 50 Ohm MMCX jack, female socket, from the MMCXV-TH series. It mates with the standard snap-on MMCX plug interface and carries a 6 GHz maximum frequency rating.
Why the High Vibration feature matters for this snap-on jack
Standard MMCX snap-on jacks can unseat under sustained shock. This one carries a High Vibration rating, which means the retention force at the snap-on interface is held to a tighter spec — it stays mated in applications where a standard MMCX would pop off. The gold body finish also helps maintain a clean ground path through the shell over repeated mates.
What the 6 GHz ceiling means for your RF budget
6 GHz is the upper limit for this interface — the VSWR stays within spec across the band, but above that the connector radiates and return loss degrades. For designs running Wi-Fi 6E (up to 7.125 GHz) this jack is not the right choice; look at the SMA or SMPM families. For sub-6 GHz applications — LTE, GNSS, ISM bands, most 5G FR1 — the 50 Ohm path through the PTFE dielectric is clean and predictable.
Through-hole mounting — what to watch on the footprint
The center contact and shield legs pass through the PCB and are soldered on the opposite side. The proper drill size for the through holes is defined in the Samtec product drawing — the center pin diameter and shield leg dimensions determine the finished hole size. A standard FR-4 board with 1 oz copper handles the ground plane connection; the shield termination is soldered, so the annular ring on the ground layer must be large enough to get a decent fillet without bridging to the center pin.
