U.FL Series●Ultra Small Surface Mount Coaxial Connectors - 1.9mm or 2.3mm, 2.4mm Mated Height
Note 1: Cable type connectors were measured with SMA conversion
adapters attached to both ends of the harness product of a
suitable 100cm cable.
Note 2: Board type connectors were mounted to a 50ø glass epoxy
board and measurements were conducted with SMA
conversion adapters attached.
