The Hirose SMP-PR(SB)-SMT-1(01) is a 50 Ohm SMP receptacle with a male pin contact, designed for surface-mount attachment to a PCB. It's part of the SMP series — a blind-mate interconnect standard used in compact RF modules, test equipment, and telecom infrastructure where board-to-board or cable-to-board connections need to be made quickly without tools. The Smooth Bore feature means this receptacle has no internal retention spring; it relies on the mating plug's own detent mechanism for axial hold, which gives a lower and more consistent insertion force across repeated mates.
Rated to 30 GHz maximum frequency, this connector covers the full Ku and K bands and reaches into the Ka band — suitable for microwave backhaul, satellite comms, and high-speed digital links where signal integrity at those frequencies is the constraint. The 50 Ohm impedance matches the standard for RF test ports and most RF system designs. The contact is beryllium copper with gold plating, and the body is brass with gold finish — a combination that delivers 1000 mating cycles, which is high for a blind-mate SMP and tells you the contact is built for field-service reconnect without fretting.
