U.FL, IPEX, IPAX, IPX,〔(Lighthorse Technologies INC catalog )〕 AMC, MHF and UMCC is a miniature RF connector for high-frequency signals up to 6 GHz manufactured by Hirose Electric Group〔(Ultra Small Surface Mount Coaxial Connectors ) - Low Profile 1.9 mm or 2.4 mm Mated Height U.FL Series. Hirose data sheet.〕 and others. U.FL connectors are commonly used in applications where space is of critical concern, most often Mini PCI cards for laptop computers. U.FL connectors are commonly used inside laptops and embedded systems to connect the Wi-Fi antenna to a Mini PCI card. Another common use is connecting GPS antennas. Female U.FL connectors are not designed with reconnection in mind, and they are only rated for a few reconnects before replacement is needed. The female U.FL connectors are generally not sold separately, but rather as part of a pigtail with a high-quality 1.32 mm doubly shielded cable, which allows for a low-loss connection. The male connectors are surface-mounted and soldered directly to the printed circuit board. They are designed to have an impedance of 50 ohms. The mated connection is only 2.5 mm high and takes as little as 3 mm2 of board space.〔(IPX datasheet )〕 Much like many other electronic components, Hirose U.FL connectors were protected by patents〔(Surface-mounted, high-frequency coaxial connector. ) US Patent 5180315 (1993)〕 and trademarks. However, compatible connectors are on the market. ==See also== Hirose W.FL 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hirose U.FL」の詳細全文を読む スポンサード リンク
