MCX RF interconnect — board-edge jack for 50 Ohm paths up to 6 GHz
The TE Connectivity 1274670-1 is an MCX-series jack, female socket, designed as a board-edge SMT interconnect for 50 Ohm RF signal paths. It carries a 6 GHz maximum frequency rating with a 0.1 dB insertion loss, making it a clean launch point for RF modules, antenna feeds, or test access ports where the MCX snap-on interface is preferred for its smaller footprint than SMA. The gold body finish and gold-over-beryllium copper centre contact support 500 mating cycles — the snap-on fastening type lets you connect and disconnect without tools, which suits field-service or calibration-access applications.
Mounting and termination — board-edge cutout, SMT solder
The Tape & Reel packaging confirms this part is intended for automated pick-and-place lines, not hand soldering.
