The Molex 0734154216 is a same-series SMP adapter — plug to jack, female socket to male pin — in a straight SMT body. It bridges two SMP connectors on the board without changing the signal path orientation, and the snap-on fastening on both ends gives a quick, tool-less mate that holds under moderate vibration. The 50 Ohm impedance and 40 GHz frequency ceiling place it in the upper band of SMP interconnect, suited for high-speed digital or microwave signal chains where a through-hole adapter would add parasitic inductance.
40 GHz is the rated maximum frequency; below that the adapter maintains the characteristic 50 Ohm impedance across the transition. SMP interfaces are designed for blind-mate, board-to-board or cable-to-board connections, and the straight body keeps the signal path short — no right-angle bend to degrade return loss. For a 40 GHz link, the adapter's own insertion loss and VSWR contribution will be small, but the SMT solder joint quality and the board launch geometry still set the practical limit. The snap-on detent provides enough retention for lab test setups or internal board interconnects, though it is not a locking mechanism for high-shock environments.
SMT Termination — Board Layout Consideration
No through-hole stubs to resonate; the ground plane can run uninterrupted under the body. The adapter is supplied in a bag, not tape-and-reel, so it is a hand-place or selective-solder item, not a full reel-fed pick-and-place part.
