RF Interconnect for Tight Spaces
The Hirose MMCX-R-PC(40) is a 50 Ohm MMCX receptacle, female socket, designed for board-mount RF interconnects where space is tight and signal integrity matters up to 6 GHz. It's the through-hole solder version of the MMCX series, with a gold-plated brass body and a beryllium copper center contact finished in gold. The snap-on fastening lets you mate and unmate quickly without a coupling nut, which is handy in dense layouts where a wrench can't swing. Rated for 500 mating cycles, it's built for applications that see regular connect/disconnect — test ports, radio modules, or antenna feeds on compact PCBs.
What the 6 GHz and 500 Cycles Mean for Your Board
The 6 GHz max frequency and 50 Ohm impedance set the signal path — this connector will pass a clean RF signal from DC through the 6 GHz band, which covers Wi-Fi, Bluetooth, cellular, and GPS bands comfortably. The 500-cycle rating means the gold-on-gold contact interface (gold body finish, gold center contact plating) will hold its contact resistance and VSWR through repeated mating, so it's a solid choice for a module that gets swapped during development or field service.
