MMCX PCB Edge-Launch Jack
The Molex 0734151475 is a 50 Ohm MMCX jack from the 73415 series, designed as a through-hole solder-mount PCB connector. It's a female socket with a snap-on fastening interface, rated to 6 GHz with 0.10 dB insertion loss. The gold-plated brass body and beryllium copper center contact with gold plating give it 500 mating cycles of reliable service.
Signal Path and Bandwidth
The 6 GHz ceiling covers Wi-Fi 6E, cellular bands up to 5G mid-band, and most instrumentation signals. Insertion loss at 0.10 dB is low enough that a single connector in the path won't eat your link budget; stack a few and the loss adds up.
500 mating cycles is the standard for MMCX — the snap-on coupling wears the detent over time. For a test fixture or a board that gets reworked a few times, that's fine. If this jack lives in a production unit that never gets unmated, the cycle life is irrelevant.
Through-hole solder mount with the shield termination also soldered — standard edge-launch layout. The single-port design takes one coaxial signal path. The gold-plated brass body gives a clean solder joint to the ground plane. No crimp or clamp here; it's a PCB connector, so the cable attaches at the other end of the trace.
