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.","metaTitle":"Amphenol RF 919-385J-51S MCX Receptacle, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 919-385J-51S MCX receptacle, female socket, 50 Ohm, 6 GHz max, board edge end launch, gold body, 500 mating cycles.
