As one of the smallest and lightest SMT ultra miniature coaxial connectors, Hirose's U.FL / U.FL(V) series provides a low mated height of a mere 2.5 / 2mm, whilst occupying only 7.7mm˛ board space.
So far, Hirose offers the U.FL with three different cable diameters, guaranteeing a VSWR of 1.3, up to 3GHz. The most recent development of U.FL, however, guarantees the excellent RF performance VSWR of 1.35, but now up to 6GHz. This makes the popular U.FL also suitable for IEEE 802.11a based wireless LAN applications.
In comparison with Hirose's previous development of the established E.FL series, the U.FL receptacles offer a space reduction of more than 18% and weighs in at a featherweight of 5.7mg. A major advantage to comparable miniature coaxial connectors is that all connectors from Hirose's FL series can be connected to their respective receptacle from any direction (360o), and an audible ""click"" gives assurance that the connectors are fully engaged.
Receptacles are available in tape & reel packaging with a gold centre contact and a silver outer shell to ensure low losses.
Think of Hirose’s U.FL for mobile phones, PDAs, GPS, wireless communication equipment, along with a host of other applications.
