The Hirose H.FL-R-SMT(10) is a surface-mount receptacle from the H.FL series, carrying a male pin center contact. The gold-plated brass center contact and silver-finished phosphor bronze body pair for corrosion resistance across the rated 50 mating cycles.
The 3 GHz limit covers 2.4 GHz ISM bands (Wi-Fi, Bluetooth, Zigbee) and GPS at 1.575 GHz, but it will not pass 5 GHz Wi-Fi or 6 GHz 5G NR bands. If your signal path runs above 3 GHz, step up to the H.FL/S-R-SMT(10) sibling, which is rated for 2 GHz — wait, that is lower. The H.FL-R-SMT(10) is actually the higher-frequency variant in the H.FL family. The 50 mating cycles mean this is a set-and-forget interconnect — fine for a module that mates once during assembly and stays paired for the product life, but not for a frequent-disconnect test port or battery connector.
