U.FL Board-Mount Receptacle — 50 Ohm, 6 GHz, SMT
The RSP-122811-01: The connector carries a 50 Ohm impedance rating and is specified to 6 GHz maximum frequency, covering 2.4/5 GHz Wi-Fi, Bluetooth, and cellular bands up to mid-range 5G NR sub-6 GHz allocations.
The 6 GHz upper frequency limit means the connector is usable for the 5.8 GHz ISM band and most sub-6 GHz 5G NR bands, though it does not cover the mmWave range above 6 GHz. The snap-on fastening provides a quick, positive mate without threads, typical for the U.FL form factor where space and assembly speed matter.
Materials and Construction
The body and centre contact are both phosphor bronze, a spring-grade alloy that maintains contact force over repeated mating cycles.
Mounting and Assembly
Surface-mount termination with solder shield termination means this part is placed and reflowed in a standard SMT line. The Tape & Reel packaging (also available as Cut Tape) feeds directly into pick-and-place machines — no manual handling required for volume builds. The single-port, single-contact design keeps the footprint small, typically occupying less than 5 mm x 4 mm of board area.
