50 Ohm MCX Jack for Board-Edge RF Routing
The Samtec MCX-J-P-H-ST-EM1 is a 50 Ohm MCX jack (female socket) rated to 6 GHz, built for board-edge mounting with SMT termination. The 6 GHz ceiling covers common wireless bands (Wi-Fi, Bluetooth, cellular, ISM) and leaves headroom for harmonic content. The snap-on fastening gives quick connect/disconnect in the field without tools — handy for test points or modular RF boards where you swap cables regularly.
Mounting Detail: Board-Edge Cutout + SMT
This MCX jack mounts into a board-edge cutout with SMT shield termination — the shield tabs solder directly to the PCB ground plane at the board edge. That placement saves interior board real estate and keeps the RF signal path short to the edge-launch trace. The centre contact also solders, so the whole assembly reflows in one pass. No through-hole posts to deal with.
The MCX-J-P-H-ST-EM1 is a female jack that mates with any standard MCX plug (male pin) using the snap-on interface. The mating half is typically an MCX right-angle or straight plug on a coaxial cable. No special keying — the snap-on collet centres the pair and holds it until you pull it apart.
