The Amphenol RF 919-119J-51AX is a 50 Ohm MCX receptacle with a female socket interface, designed for right-angle through-hole PCB mounting. This connector is suited for board-edge RF launch applications where a low-profile, quick-connect interface is needed — common in GPS modules, wireless infrastructure, and test equipment.
What the 50 Ohm and 6 GHz Ratings Mean for Your RF Link
The 6 GHz maximum frequency means this connector can pass L-band, S-band, and C-band signals up to the lower 6 GHz region without significant mismatch loss. The 0.1 dB insertion loss per mated pair is low enough that you can treat it as negligible in a short jumper or pigtail; it becomes a budget item only in long cascaded runs.
Right-Angle Mount and Board Layout Fit
The centre contact and shield legs are solder-terminated, so the PCB footprint must provide a ground-plane clearance for the 50 Ohm trace transition — the datasheet footprint is the reference. The snap-on fastening means no torque tool is needed for mating; the connector locks with an axial push and releases with a straight pull.
