50 Ohm RF Launch, 6 GHz Ceiling
The Samtec MCX-J-P-H-ST-SM1-TR is a 50 Ohm MCX jack — female socket, snap-on coupling, surface-mount termination.
SMT Footprint and Board Launch
This is a surface-mount part — the contact and shield are soldered directly to the PCB pads. The SMT termination means the connector is reflow-soldered alongside other surface-mount components, which saves a wave-solder pass. The board launch geometry — pad size, ground-plane clearance, and via pattern around the centre pin — must be designed for 50 Ohm impedance to keep the return loss low up to 6 GHz.
