MCX Receptacle, 50 Ohm, 6 GHz — Board Edge End Launch
The Amphenol RF 919-385J-51S is a 50 Ohm MCX receptacle with a female socket interface, designed for board edge end launch mounting. It is a single-port connector rated to 6 GHz maximum frequency, making it suitable for RF modules, antenna feeds, and test points where a compact snap-on interconnect is needed.
Mounting and Termination — Board Edge End Launch with Solder
The board edge end launch style places the connector at the PCB perimeter, with the signal path exiting parallel to the board surface. This is common for RF modules where the connector must align with an enclosure cutout or mate with a cable assembly approaching from the side.
Mating Interface and Mechanical Retention
The snap-on fastening provides quick push-to-connect mating with a corresponding MCX plug.
Temperature Range and Dielectric
The wide temperature envelope does not require derating the 50 Ohm impedance or the 6 GHz frequency limit — the PTFE maintains stable dielectric constant across the full range.
