SMP Jack for RG-405 Semi-Rigid — 40 GHz, Blind-Mate Interface
The Molex 0734153033 is an SMP-series jack, female socket, designed for direct solder termination to RG-405 (.086 inch diameter) semi-rigid coaxial cable. The SMP interface is a blind-mate, push-on (snap-on) coupling that allows dense board-to-board or module-to-backplane RF interconnects without the thread engagement of an SMA. The dielectric is PTFE, chosen for low loss and stable phase over temperature. Shield termination is via solder to the outer conductor of the semi-rigid cable — no crimp tool needed, just a controlled soldering station and the correct prep dimensions for the RG-405 dielectric.
Cable Prep and Termination
This jack is built specifically for RG-405 (.086 inch) semi-rigid cable — the center conductor, dielectric, and outer conductor dimensions are matched to the connector's bore and pin geometry. The shield is soldered directly to the connector body; no ferrule or crimp sleeve is involved. The contact termination is also solder, meaning the center pin is soldered to the cable's center conductor after the dielectric is stripped to the correct length. The manufacturer's application note for the 073415 series gives the exact strip dimensions — critical to maintain the 50 Ohm impedance through the transition. Because the connector is a right-angle body, the cable exits at 90 degrees to the mating axis. This is the common orientation for board-edge or module-face mounting where the cable routes along the chassis wall. The free-hanging mount means there are no panel-mount threads or flange holes — the connector relies on the cable's own stiffness and the mating connector's retention to stay in place.
The base product number is 073415, and this specific variant is the right-angle, RG-405, snap-on SMP jack in a tray package.
