The Hirose U.FL-R-SMT-1(80) is a 50 Ohm surface-mount receptacle from the U.FL series, designed as the board-side half of a snap-on RF interconnect for compact wireless modules. It uses a male centre pin — the plug side carries the female contact — and terminates by reflow soldering the shield tabs and centre pin to the PCB. The 6 GHz frequency ceiling covers WiFi 6E, Bluetooth, GPS, and cellular antenna feeds where the board footprint budget is tight.
Why the 30-cycle mating life matters for field service
The 30 mating cycles rating is the practical reconnect limit before the gold plating on the brass centre contact wears through to the base metal. For a production antenna cable that mates once and stays, 30 cycles is generous. For a test jig or a field-swappable radio module that gets disconnected every board swap, 30 cycles means you budget for a connector replacement after a few dozen service events. The snap-on fastening type gives a positive tactile lock — you feel the click when the plug seats — but the retention force drops as the plating wears.
