The Molex 0734060595 is a series 73406 SMP adapter configured as a jack-to-jack (female-to-female) in-line barrel. It is designed for 50 Ohm controlled-impedance interconnects and is rated to 40 GHz, covering applications through Ka-band and into millimeter-wave test and system integration. Both ends use snap-on coupling, the standard SMP blind-mate interface. No threads, no torque wrench — the connector pushes on and locks with a detent. The dielectric is PTFE, a low-loss material that maintains the 50 Ohm impedance across the full 40 GHz band.
It is built to maintain a consistent 50 Ohm transmission line through the transition, so it belongs in RF and microwave signal chains where impedance mismatch would cause reflections and insertion loss. The 40 GHz frequency rating means it supports signals up to the upper edge of Ka-band; above that the PTFE dielectric and the SMP interface geometry begin to limit performance. For sub-6 GHz or lower-frequency RF work, this adapter is over-specified but fully usable. The snap-on fastening on both ends is the SMP standard for blind-mate and push-on connections. It allows quick connect and disconnect without tools, but the retention force is lower than a threaded interface — suitable for rack-and-panel or cable assemblies where vibration is moderate and the connector is not subject to heavy cable strain. The beryllium copper body and gold plating support repeated mating cycles without degrading contact resistance or signal integrity.
